What Road Top actually sells
Road Top sells CarPlay and Android Auto retrofits for specific vehicles. The catalogue is small and focused: 49 products, of which 48 are vehicle units and one is a twelve-piece radio removal tool kit. The company says it was founded in 2014 and holds a Chinese national high-tech enterprise designation.
The range splits into two lines, and knowing which one you need is the first thing to settle.
The first line is add-on modules. These sit behind your existing factory screen and add wireless CarPlay, Android Auto and phone mirroring to it, while the original controls and displays keep working. Thirteen makes are covered: Mercedes-Benz, BMW, Audi, Mini, Porsche, Land Rover, Jaguar, Lexus, Ford, Cadillac, Buick, Chevrolet and Toyota.
The second line is replacement screens running Linux, for cars that never had a factory screen at all. That line is much narrower — only Mercedes-Benz, BMW and Audi — and the brand positions it exactly that way: the right choice if your car has no original screen.
The thing that decides everything: your head-unit generation
This is the heart of the purchase and the reason we would not buy from this brand casually.
Road Top's catalogue is organised by factory infotainment generation, not by car, so the first thing to pin down is which generation sits in your dashboard. These are the generations you need to identify, not a list of what fits: For BMW, that means CCC, CIC, NBT or EVO. For Mercedes-Benz, NTG 4.5/4.7 versus NTG 5.0 and later. For Ford, SYNC 1, 2 or 3. For Porsche, PCM 3.0, 3.1 or 4.0. For Cadillac, HMI 2.0/2.5. For Audi, a longer list including RMC, MIB, BNav, HNav and basic radio.
The brand states its exclusions clearly where it matters most. Its Mercedes module is not compatible with NTG 4.0 head units from 2008 to 2010, and not compatible with NTG 5.0, 5.1 or 5.2 from 2016 to 2019. Its Ford module does not fit cars running SYNC 1 or SYNC 3. Those are useful, specific statements and we credit them.
And here is the problem. There is no fitment checker on the site. No vehicle selector, no year-make-model dropdown, no VIN lookup. More importantly, there is no guide anywhere explaining how to work out which generation your own car has, and no page telling buyers to confirm compatibility before ordering. The purchase requires knowledge the brand sells around but does not help you acquire.
So before you spend anything: identify your head unit yourself. Your VIN decoded through a marque-specific tool, your original window sticker, or an owners-forum thread for your exact build year will get you there. Do that first. Do not order a wireless CarPlay module and hope.
Model-year coverage, and where it stops
Where the brand does publish years, it publishes them per model, and the ranges are reasonably precise. Its BMW NBT/EVO module lists 1 Series F20/F21 at 2013 to 2020, 3 Series F30 and related chassis codes at 2013 to 2020, X5 F15/F85 at 2014 to 2020, and so on down the range including the i8 and several Mini chassis.
Lexus coverage runs from 2014 to 2019 across ES, NX, RX, GS, RC, CT, LS, LX and UX, with the 2018-onward UX the newest thing listed. Buick is the most precisely specified of all, naming screen size and years per model. Land Rover and Jaguar are listed at 2012 to 2018.
Two caveats. First, several products publish no model years at all — the Ford, Cadillac, Chevrolet and Porsche listings name models but not year ranges. Second, coverage broadly stops around 2019 or 2020. If your car is newer than that, it is not on these lists, and nothing on the site suggests newer support is coming.
One inconsistency we will flag rather than smooth over: the Porsche product is titled for PCM 3.0 and 3.1, but its own variant list includes PCM 4.0. Those two statements disagree, and we would want that confirmed in writing before ordering.
The other choice axes
If you are buying a replacement screen rather than a module, size is a real decision — the Linux screens come in 8.8-inch, 10.25-inch and 12.3-inch options depending on the vehicle, with some sizes shown as unavailable.
On the Lexus module, the variant you need is set by your factory controller type rather than your year: knob, joystick, large touchpad or small touchpad. Check which one is in your centre console before selecting.
Camera and HDMI expansion is the last axis worth noting. Several modules advertise support for aftermarket reversing, dashcam and 360-degree camera inputs plus an HDMI input. If adding a reversing camera later is part of the plan, that belongs in the decision now.
Installation: what the brand claims, and what it never addresses
Road Top repeats the same installation claim across its module pages: the original car wiring is plug and play, with no cutting, no splicing and no damage to the vehicle. On its Buick and similar listings it adds that original console functionality is retained.
What the brand never says, anywhere, is whether you need a professional installer. It does not require one, recommend one, or discourage one. It sells a radio removal tool kit for $20, which implies owner installation, but it never states that.
There is also no installation documentation on the site. No install page, no manual, no video, no tool list, no time estimate, no difficulty rating. Customer reviews reference QR-coded videos inside the box, so documentation appears to ship with the product — but you cannot read it before buying.
And the brand does not address whether installing the unit affects your vehicle warranty, or whether an installed-then-removed unit can still be returned. For car electronics, that second gap is the one that matters, and it is unaddressed.
Prices, shipping, and the returns clause that changes the maths
Everything is in US dollars. The cheapest vehicle unit is the Toyota module at $149, the most expensive is the Audi Q5 screen at $239, and most of the catalogue sits between $169 and $220. The tool kit is $20.
Shipping is genuinely free worldwide with no minimum, dispatched within 24 hours of payment, with a three-to-seven-day transit estimate for both domestic and international orders. Goods ship from China. No carrier is named. The brand does not deliver to PO boxes, and international customers are responsible for customs duty and taxes — which sits awkwardly against the "TAX FREE" wording in the product titles, so budget for duty regardless of what the title says.
Now the clause to read before you buy anything here. The returns policy runs 60 days, which sounds generous. But the same policy states that only regular-priced items can be refunded, and that anything discounted by 40% or more is final sale. Every product on the site is currently listed at roughly 67% to 71% below its stated regular price. On a plain reading of the brand's own terms, that places the entire catalogue outside the refund policy.
There is more in the same document. Defect claims must be raised within 72 hours of receipt — which, for a part that may sit in a box until you can book installation time, effectively overrides the headline 60-day figure. Returns carry a 20% restocking fee, waived only if you exchange for something of similar value. You pay return postage, and it is deducted from the refund. Exchanges are offered only for defective or damaged items, so a wrong-fitment mistake is not an exchange.
Warranty is published twice with two different numbers: the returns policy says one year, while product pages and the About page say two years of quality assurance. The brand does not reconcile them, and publishes no list of what voids the warranty.
What Road Top does not publish
No screen resolution for any product. No processor, RAM or storage figures. No Android version, despite advertising Android Auto. No brightness, viewing angle or operating-temperature data. No firmware update policy. No supported-Android-phone list.
On the company side: no postal address, no phone number, and three different contact identities across the site, including a free webmail address as the primary support channel. The FAQ and warranty URLs both return 404. The privacy policy still contains unfilled template placeholders.
We would normally fill some of those gaps from a spec sheet or a retail listing. We are not going to, because inventing a resolution figure for a screen is exactly the kind of thing that makes affiliate reviews worthless.
Who should skip Road Top
Anyone whose car is newer than about 2020, or is not among the twelve makes listed.
Anyone who cannot confirm their own head-unit generation. There is no checker and no identification guide, and a wrong-fitment order is not exchangeable.
Anyone who needs published specifications before buying. Resolution, processor and memory are simply not stated.
Anyone who wants a safety net. The 40%-off final-sale clause arguably covers the whole catalogue, and the defect window is 72 hours.
Anyone shipping to a PO box, or anyone who cannot absorb customs duty on a $150–$240 item.
Our view
The hardware proposition is legitimate and the free worldwide shipping is real. But this is a purchase where the buyer carries all the research burden, and where the brand's own returns terms give very little room for a mistake. If you know your head-unit generation with certainty, the odds are good. If you are guessing, the 20% restocking fee and the final-sale clause will make that guess expensive.
