Overview

The OiLiehu RM 9.7″ Double Din Car Stereo is a budget-minded Android head unit that gives older vehicles a genuine smartphone-era upgrade without requiring a costly factory replacement. The standout feature right away is that vertical 9.7-inch screen — it's noticeably taller than the typical widescreen layout, which makes a real difference when you're glancing at a map mid-drive. Running Android 13, this vertical touchscreen head unit can install navigation apps, stream music, and handle media in ways a basic factory radio simply can't. OiLiehu isn't a household name, so don't expect Kenwood or Pioneer fit-and-finish, but the hardware feels reasonably solid. Just be aware your vehicle may need a dash adapter kit before installation is straightforward.

Features & Benefits

The vertical screen orientation is what buyers notice first, and it earns its keep when you're navigating — a taller map view means less scrolling and more road context at a glance. This Android car stereo ships with an offline North American map built in, though connecting to a Wi-Fi hotspot and using Google Maps or Waze is where routing gets accurate and reliable. Bluetooth 4.0 handles hands-free calls and audio streaming without fuss, and the auto phonebook sync is a nice touch. Android and iPhone users both get mirror link via USB, though iPhone owners should know upfront: it's one-way mirroring only, not CarPlay. The SWC learning function lets you keep your steering wheel controls active, and the backup camera input switches automatically when you shift into reverse.

Best For

This Android car stereo makes the most sense for drivers upgrading from a bare-bones factory unit in an older vehicle — particularly one that lacks Bluetooth, navigation, or any kind of touchscreen interface. If your dash has a standard double-din opening and you're comfortable poking around Android settings to connect Wi-Fi or sideload an app, you'll get real value here. The taller vertical display also makes this a solid pick for drivers who spend a lot of time on unfamiliar routes and find conventional widescreen maps cramped. It's less ideal for tech-averse buyers or anyone expecting plug-and-play CarPlay, and installation may require a trim adapter depending on your vehicle — worth budgeting for before you order.

User Feedback

Buyers consistently praise the screen size — it genuinely impresses for the price — and most find Bluetooth pairing straightforward from day one. The backup camera auto-switch gets specific appreciation from users who didn't expect it to work as cleanly as it does. On the flip side, 1GB of RAM is a real constraint; users report noticeable lag when jumping between navigation and music apps simultaneously. The built-in offline map gets mixed marks for accuracy, and most experienced owners recommend connecting to a hotspot for anything beyond basic route following. A handful of buyers ran into fitment headaches during installation. That said, OiLiehu's technical support is mentioned favorably across multiple reviews, which counts for something when you're troubleshooting a wiring harness at 10pm.

Pros

  • The 9.7-inch vertical screen gives maps noticeably more height, reducing the need to glance away from the road.
  • Android 13 lets you install Google Maps or Waze for accurate, real-time navigation beyond the built-in offline map.
  • Backup camera input switches automatically on reverse, a genuinely useful safety feature that works as advertised.
  • Bluetooth pairing is straightforward, and auto phonebook sync makes hands-free calling reliable from day one.
  • The steering wheel control learning function preserves your existing button layout without requiring new hardware.
  • Android users get full bidirectional mirror link, enabling real phone control directly from the touchscreen.
  • Built-in offline North American map means basic navigation still functions without any data or hotspot connection.
  • Wi-Fi support opens the door to app installs and live navigation, keeping the unit practically extensible.
  • OiLiehu's technical support team draws consistent praise — a genuine plus when dealing with a lesser-known brand.
  • The overall feature set relative to the asking price is genuinely hard to match in the budget double-din category.

Cons

  • With only 1GB of RAM, running navigation and audio simultaneously can trigger lag that disrupts the driving experience.
  • iPhone users get one-way mirroring only — there is no CarPlay support, and that limitation will not change via an update.
  • The built-in offline map has questionable routing accuracy; reliable navigation really depends on a live Wi-Fi or hotspot connection.
  • Many vehicles require a dash trim adapter kit, which adds cost and installation complexity that buyers often don't anticipate.
  • The vertical form factor, while great for map visibility, can create fitment headaches in dash openings designed for standard horizontal units.
  • OiLiehu is a relatively unknown brand with limited long-term durability data compared to established names like Pioneer or Kenwood.
  • 16GB of internal storage fills up faster than expected once navigation apps, media files, and system data accumulate.
  • The Android interface involves a real setup curve — non-Android users may find the initial configuration process frustrating.
  • No dedicated DSP audio processing means sound customization is limited to basic EQ adjustments, which won't satisfy critical listeners.

Ratings

Our AI-driven scoring for the OiLiehu RM 9.7″ Double Din Car Stereo was generated by processing verified buyer reviews from multiple global markets, with spam, bot activity, and incentivized feedback actively filtered out before any score was calculated. The results reflect an honest cross-section of real-world ownership experiences — both the genuine strengths and the friction points that affect daily use. Where this vertical touchscreen head unit earns high marks and where it falls short are both transparently captured in the category breakdowns below.

Value for Money
88%
Buyers consistently report being surprised by how much functionality this Android car stereo delivers at its price tier. A large touchscreen, built-in GPS, Bluetooth, and backup camera compatibility bundled together would cost considerably more from a mainstream brand. That gap in perceived value is what drives the bulk of positive sentiment.
The value calculation gets murkier once you add a dash trim adapter, vehicle-specific wiring harness, and a separate backup camera — all commonly needed and sold separately. For some buyers, the total out-of-pocket cost drifts closer to mid-range head unit territory, which meaningfully changes the math.
Screen Quality
83%
The 9.7-inch vertical display consistently draws positive comments from drivers who spend significant time navigating — the extra height shows more of the road ahead on a map compared to a standard widescreen layout. Brightness and touch response are considered strong for the price, and the 2.5D glass gives it a more premium feel than the cost implies.
A portion of buyers note that brightness can feel insufficient under direct midday sun, requiring manual adjustment to maintain readability. The display quality, while impressive at this price, does not match the clarity or color accuracy of panels found on Kenwood or Sony head units in the same category.
GPS & Navigation
62%
38%
When connected to a Wi-Fi hotspot and running Google Maps or Waze, the navigation experience on this vertical touchscreen head unit is genuinely capable — the tall screen makes lane guidance and junction views easier to read at a glance. Drivers who commute on familiar routes find the live app integration reliable and practical day to day.
The pre-installed offline map receives consistently mixed-to-negative feedback for route accuracy — several users report being directed onto outdated roads or missing recent road changes entirely. Without a hotspot connection, the navigation experience is unreliable enough that drivers in areas with poor data coverage will find this a meaningful daily limitation.
Installation Experience
54%
46%
Buyers with prior car audio experience and the right vehicle generally report a manageable install, especially in cars where the double-din opening is a standard size. Several users note that the included wiring harness and instruction documentation are clearer than expected for a budget brand.
The vertical form factor trips up a significant portion of buyers — standard dash kits don't account for the taller cutout height, requiring vehicle-specific research before purchase and often an additional adapter order after. CAN bus vehicle owners face a further hurdle, as the steering wheel control function won't work without a separate module. Many buyers underestimate the total complexity involved.
App & OS Performance
57%
43%
Android 13 as a platform gives this head unit an openness that buyers genuinely appreciate — being able to install a preferred navigation app or music player makes it feel adaptable in a way that locked-down proprietary systems don't. For light, single-app usage, the experience is functional and largely frustration-free.
The 1GB of RAM ceiling is where user frustration concentrates most heavily — running navigation while streaming audio and keeping a secondary app in the background produces lag that many find disruptive during longer drives. A subset of users reports the system occasionally needs a full reboot to clear memory and restore normal response speed.
Bluetooth Performance
79%
21%
Most users get the unit paired to their phone within minutes of installation, and the auto phonebook sync works reliably for hands-free calls during daily commutes. Audio streaming via A2DP is clean and stable enough for casual listeners, and incoming call handling is consistently praised for being smooth and interruption-free.
Bluetooth 4.0 is a noticeably older standard, and a vocal segment of users reports occasional dropout or re-pairing issues, particularly with newer flagship phones that favor Bluetooth 5.0 or higher. The lack of a more modern Bluetooth version feels like an area where a modest engineering investment could have meaningfully improved long-term reliability.
Build Quality
63%
37%
For a budget-tier head unit, the overall construction holds up reasonably well in everyday use — the bezel feels solid enough, and the touchscreen glass sits flush with a finish that looks better in person than the price implies. Buyers who have used entry-level head units from other no-name brands report this one feeling a step above.
The plastics and internal components don't match the tactile feel of Pioneer or Kenwood units at a similar price, which some buyers notice immediately on unboxing. A small subset of users also reports quality control inconsistency — units that arrive with minor cosmetic defects or physical buttons that feel less precise over time.
Mirror Link
66%
34%
Android users with a compatible USB cable consistently report a smooth bidirectional mirror link experience — controlling phone apps from the head unit's touchscreen while driving feels intuitive and reduces the need to reach for the phone directly. For Android-centric households, this feature alone justifies a significant portion of the purchase decision.
iPhone owners are the clear losers here — the one-way iOS mirror link means you can see your phone screen on the unit but cannot control anything from the touchscreen, which many find nearly pointless in practice. Users expecting CarPlay-like functionality are routinely disappointed, and this mismatch is a frequent driver of negative reviews from iPhone households.
Backup Camera
82%
18%
The automatic camera switching when reversing is one of the most universally praised aspects of the OiLiehu double-din unit — drivers who have never had a backup camera before describe the experience as immediately confidence-boosting in tight parking situations. The transition from main screen to camera feed is fast and reliable, with no manual input required.
The camera itself is not included in the box — buyers need to source a compatible unit separately, which adds cost and requires additional wiring work at install time. Image quality on the camera feed depends entirely on the third-party camera chosen, meaning a poor camera selection can undermine what is otherwise a well-implemented integration.
Steering Wheel Control
74%
26%
Drivers who successfully program the SWC learning function report genuine satisfaction — being able to control volume, tracks, and calls from the steering wheel without rewiring the car is a meaningful daily convenience. The programming process, while requiring some patience, is described as straightforward for most standard steering wheel control setups.
Vehicles equipped with a CAN bus steering wheel control system require a separate CAN bus adapter to make the function work — a requirement that catches many buyers off guard at installation time. A minority of users with non-standard button layouts also report incomplete programming, where some buttons are recognized correctly but others are not.
Audio Quality
71%
29%
For everyday listening — podcasts, streaming radio, or a Bluetooth music playlist on a commute — the audio output is clean and adequate. The built-in EQ settings give enough adjustment range for most users to find a comfortable sound profile, and FM reception is praised for being stable across most frequency ranges.
Audiophile-minded buyers or drivers with upgraded door speakers will find the lack of dedicated DSP processing limiting — the basic EQ is no substitute for proper signal tuning. Some users also report that maximum volume levels on certain inputs can introduce audible distortion, particularly noticeable in larger cabin vehicles where higher output is needed to fill the space.
UI & Ease of Use
68%
32%
Android-familiar users tend to adapt quickly — the home screen layout and app drawer behave much like a standard Android tablet, keeping the learning curve shallow for the majority of buyers. Features like wallpaper customization and brightness adjustment are appreciated by users who like personalizing their in-dash setup beyond the factory defaults.
First-time Android head unit owners and non-Android phone users report a noticeably steeper adjustment period, with initial setup — connecting Wi-Fi, configuring accounts, sideloading apps — taking longer than expected. The interface can also feel sluggish during the first few minutes after a cold boot, before the system has fully settled into its working state.
Technical Support
77%
23%
Multiple buyers specifically mention that OiLiehu's support team responded quickly and helpfully to wiring and compatibility questions — an experience that stands out in the budget head unit category, where post-sale support is often minimal or non-existent. Lifetime technical support is a genuine differentiator that several users credit with preventing a return.
Response quality appears inconsistent based on issue complexity — straightforward wiring questions tend to be resolved quickly, while more nuanced problems around app compatibility or Android configuration receive slower and sometimes incomplete guidance. International buyers also note that language barriers can occasionally affect the clarity of support responses on technical matters.
Wi-Fi & Connectivity
73%
27%
Once connected to a stable hotspot, Wi-Fi unlocks the full potential of this Android car stereo — live navigation apps work reliably, app updates apply automatically, and the unit behaves much more like a proper Android device. Dual USB ports and an AUX input also give flexible options for media sources well beyond wireless playback.
The unit has no built-in SIM slot, so Wi-Fi performance depends entirely on the driver's phone hotspot — in areas with weak signal or data throttling, live navigation and app responsiveness degrade noticeably. Drivers who regularly pass through coverage dead zones will find themselves relying on the offline map, which carries its own well-documented accuracy limitations.

Suitable for:

The OiLiehu RM 9.7″ Double Din Car Stereo is a strong fit for drivers who want to modernize an older vehicle without spending heavily on a branded head unit. If your car has a standard double-din slot and currently lacks Bluetooth, GPS, or any kind of touchscreen, this Android car stereo bridges that gap competently. The unusually tall vertical screen is a genuine advantage for anyone who spends significant time navigating unfamiliar roads — maps are easier to read at a glance compared to the cramped layouts on standard widescreen units. Android users will particularly appreciate the bidirectional mirror link, which lets them control phone apps directly from the dashboard display. This vertical touchscreen head unit also suits budget-conscious buyers who are comfortable doing light Android setup — connecting Wi-Fi, installing a preferred nav app, adjusting EQ — and don't need everything to work without any initial configuration.

Not suitable for:

The OiLiehu RM 9.7″ Double Din Car Stereo is not the right call for iPhone users expecting a CarPlay experience — the iOS mirror link is strictly one-directional, meaning you can view your phone screen on the unit but cannot interact with it in reverse. Buyers hoping for a true plug-and-play install should also look elsewhere; depending on your vehicle, a dash trim adapter or wiring harness adapter may be required, adding unexpected cost and effort before you even power it on. The 1GB of RAM is a hard ceiling — if you typically keep navigation running while streaming music and fielding calls, lag and occasional app crashes are realistic outcomes. This Android car stereo is equally ill-suited for tech-averse drivers who want a simple, no-configuration experience, since getting the most out of an Android head unit requires a genuine willingness to tinker. Buyers prioritizing premium sound quality or an OEM-level fit and finish should also temper expectations, as build quality and audio refinement don't match what established names deliver.

FAQ

As long as your vehicle has a standard double-din dash opening, the unit should fit. That said, the vertical form factor is taller than a typical horizontal double-din unit, so some vehicles will need a specific dash trim adapter to fill the gap around the edges. Before ordering, it's worth measuring your opening and confirming that a compatible adapter exists for your make and model.

Neither CarPlay nor Android Auto is supported. iPhone users can mirror their screen to the display via a USB data cable, but the connection only goes one way — you see your phone on the screen, but you can't control it from the head unit. Android users get a better arrangement with bidirectional mirror link, meaning control works in both directions over USB.

Yes. Since the unit runs Android 13, you can connect to Wi-Fi and download Google Maps, Waze, or any other navigation app from the Play Store. That's actually the most reliable way to navigate — the pre-installed offline map works in a pinch, but live app-based routing is noticeably more accurate and up to date. Most users set this up within the first few days and use it as their primary navigation method.

It's a decent backup option but not something to rely on as your main navigation tool. User feedback on the offline map's accuracy is mixed — road data can be outdated, and routing decisions are sometimes questionable. Pairing this Android car stereo with a mobile hotspot and using a live navigation app is the recommended setup for anyone who navigates regularly.

It's manageable for anyone comfortable with basic car audio work, but it's not a straightforward drop-in swap for every vehicle. You'll need to match the wiring harness to your car's connector, and depending on your dash configuration, a trim adapter may be required to fill the space around the unit. The OiLiehu RM 9.7″ Double Din Car Stereo's taller-than-standard cutout is a notable wrinkle — some buyers find that generic off-the-shelf dash kits don't quite account for the vertical height, which requires a bit of extra research before you start pulling panels.

Yes, the backup camera itself is sold separately — the unit provides the input and the automatic switching logic, but it doesn't include a camera in the box. Once you wire a compatible camera into the camera input, the display will automatically switch to the camera feed every time you shift into reverse, which users consistently describe as one of the more satisfying parts of the setup.

In most cases, yes. The SWC learning function lets you connect your vehicle's steering wheel control wire and then program the unit button by button. The one exception is vehicles that rely on a CAN bus system — those require a separate CAN bus adapter and won't work with a direct connection. For standard setups, the programming process is fairly simple and well-documented.

It depends on how you use the unit. Playing music or running a single navigation app at a time is generally fine. Where the limitation shows up is when you're switching between apps quickly, running navigation while streaming audio, or trying to do much at once — that's when noticeable lag appears. If your driving routine involves heavy app switching, a unit with 2GB or more of RAM would serve you better.

OiLiehu offers lifetime technical support, and buyer feedback specifically highlights their support team as genuinely responsive — which is a meaningful differentiator at this price point. If you hit a snag with wiring, app compatibility, or feature setup, reaching out to their support channel is a reasonable first move before assuming there's a hardware problem.

Yes, through the dual USB inputs. Plugging in a USB flash drive gives you extra space for music, video, and other media files. Keep in mind this expands your external media storage, not the internal Android storage used for app installation — your installed apps still share the 16GB ROM. For users with large music libraries, a USB drive is a practical and inexpensive workaround.
