There is a large and growing market in retrofitting modern infotainment into cars that were otherwise fine. A well-kept Audi A6 from the middle of the last decade drives beautifully and has a screen and interface that feel a decade old, because they are. Replacing that screen is one of the highest-impact upgrades available for the money - and it is also one of the easiest ways to create an expensive electrical problem in a car you like.
The Roadtop 12.3-inch HD Screen for Audi A6 / A7 is $220.00, listed down from $699.00, with free worldwide shipping. The proposition is appealing. The product page is unusually sparse, and that is the review.
Published specification
| Specification | Value |
|---|---|
| Screen size | 12.3 inch, ultra-thin |
| Vehicle fitment | Audi A6 / A7 |
| System variants | RMC, HN+, MHI2 (select to match your car) |
| Shipping | Free worldwide; listed as tax free |
| Returns | 60-day return and exchange |
| Warranty | 2-year quality assurance |
| Support | Stated permanent technical support |
| Price | $220.00 (regular $699.00) |
That table is not an abridgement. It is essentially everything the listing publishes.
The one genuinely useful thing on the page: the system variants
Credit where it is due - offering RMC, HN+ and MHI2 as separate options is the correct approach, and it tells you Roadtop understands the problem. Audi used several different infotainment generations across the A6 and A7 range, and they differ in connector, bus protocol and software behaviour. A screen built for one will not simply work in another. Sellers who list a single universal part for these cars are the ones to avoid.
A 12.3-inch panel is also the sensible size target - it matches the proportions of the factory dash aperture in these cars rather than sitting proud of it like a tablet stuck to the console, which is what the cheapest retrofits look like.
The 60-day return window and 2-year warranty are, on paper, considerably better than the category norm. Retrofit electronics from unbranded sellers routinely come with 14 days and no warranty at all. If those terms are honoured, they materially reduce the risk of a purchase like this.
Three honest drawbacks
1. The listing publishes no technical specifications at all. This is the central problem. There is no resolution, no brightness figure, no processor or RAM, no operating system or version, no statement of whether CarPlay and Android Auto are wired or wireless, and - most importantly - no confirmation that factory functions are retained. That last point is the one that ruins these installs: does your reversing camera still work? Your parking sensors display? Steering-wheel controls? Vehicle settings menus? DAB? Amplifier and sound settings? A screen that gives you CarPlay but loses your reversing camera is a downgrade. Get written confirmation of exactly which factory functions survive before you order.
2. After-sales support runs through a personal Gmail address. The product page states that the after-sales engineer contact for roadtop.com customers is an @gmail.com address. For a $220 vehicle electronics product carrying a two-year warranty and promising "permanent technical support", that is worth noticing. It is not proof of anything - small operations do run this way - but a free consumer email account is not the infrastructure of a company set up to honour multi-year warranty claims at scale. Weigh the generous-sounding warranty terms against how they would actually be administered.
3. You need to know which head unit your car has, and the listing does not help you find out. RMC, HN+ and MHI2 are not badged anywhere on the dashboard. Ordering the wrong variant means a return, and returns on international shipments are slow and sometimes expensive regardless of the stated policy. Before buying, identify your system - your VIN, the vehicle's build data, or an Audi dealer or specialist can confirm it. Do not guess from the model year alone.
Two further cautions. First, "TAX FREE" describes what the seller charges, not what your customs authority may charge on import. In many countries duty and VAT on an incoming parcel are the recipient's legal responsibility, and a seller's label does not change that - budget for the possibility. Second, and more seriously: this is a dashboard-out installation on a modern car with a CAN bus. Fitting it involves disassembling interior trim and connecting to vehicle electronics, and doing it badly can cause fault codes, drain issues, or airbag and warning-light problems. Unless you have done this work before, have it fitted by an auto-electrician, and check how your manufacturer or extended warranty treats aftermarket infotainment before you start.
Who should buy it - and who should not
Buy it if you have confirmed your exact head unit variant, you have a competent installer lined up, and you have received written confirmation from Roadtop about which factory functions are retained. For an out-of-warranty A6 or A7 that you plan to keep, $220 for a modern 12.3-inch interface is a strong value proposition if the part is right.
Skip it if your car is still under manufacturer warranty, if you are not certain which system it has, if you would be installing it yourself without experience of automotive electrics, or if the absence of any published specification bothers you - as it reasonably might at this price.
Verdict
Roadtop has the fundamentals right: correctly segmented fitment options, an appropriate screen size, and stated terms that are better than the category average. What it has not done is give buyers the information needed to make a confident decision - no specifications, no functional compatibility list, and a support channel that does not match the promises attached to it. Ask the questions, get the answers in writing, and the 60-day window is your safety net. Order blind and you are gambling with your dashboard.
