Full-Screen CarPlay, Certification & Head Unit Retrofits

We read and archive a full backup of the original firmware before any write, so there is always a rollback path. We also require a support power supply and verify battery voltage first, because voltage drop mid-write is the main real-world cause of bricked units. If a unit is already damaged — by a failed flash elsewhere or a hardware fault — we diagnose it first and tell you honestly whether recovery is possible, before you pay for anything.

Our work follows factory specifications and uses OEM-grade firmware and parts, and we keep your original backup so the system can be restored. That said, warranty treatment varies by country and by dealer, and we cannot make claims on a manufacturer's behalf. If your car is still under factory warranty, tell us before booking and we will explain the realistic options for your specific market.

The VIN is the single most useful thing — it tells us the chassis, engine, equipment level and market. A photo of the current centre screen and a screenshot of the software version helps too. With those we can confirm compatibility and give a fixed written price, usually within working hours.

All HU6 (NTG6 / NTG6.5) head units — fitted to most 2018–2023 models including C-Class, E-Class, GLC, GLE, A-Class and CLA. It is a firmware activation, so no module is added and nothing is dismantled. Older NTG5 / NTG5.5 and NTG4 cars need a head unit retrofit to HU6 or HU7 first, which we also supply as a pre-configured kit.

For software work — CarPlay activation, coding, certification, firmware updates — no. Everything runs remotely through your OBD port. For hardware retrofits we usually ship a complete pre-configured and pre-certified kit to you, which you or your installer fit; you do not send us your original unit. Ship-in service applies only to repair and brick-recovery jobs.

Kits ship by DHL / FedEx with tracking, and we state the declared value and any duties that may apply in your country before you order — those costs are yours, and we will not hide them. Remote sessions are scheduled in your time zone, including evenings and weekends. Payment is by PayPal, Wise or SWIFT transfer for overseas customers.

Full-screen CarPlay activation is usually around one hour; coding packages one to two hours; certification and multi-module jobs can take up to three. Keep the vehicle stationary with the ignition on and do not start driving mid-session. Once we have verified the functions together, the car is ready to use normally.

A dealer performing a full software update can overwrite activated features — this is a property of the vehicle software, not of our work. Because we keep your original backup and your job record, re-activation is straightforward and covered under warranty within the warranty period. We will tell you exactly which items are affected before you take the car in for dealer work.

Message us with your shop name, region and the diagnostic tools you use. We send the partner rate card the same day, your first job can run as a paid trial, and most partners are operational within 24 hours. There are no registration fees, deposits or minimum volumes — see the Remote Programming Support section for the full workflow.

Mainland China: WeChat Pay and Alipay, with an invoice available on request. Overseas: PayPal, Wise and SWIFT bank transfer. B2B partners can move to monthly invoicing with net-30 terms after the first few settled jobs. We agree the total in writing before work starts — no surprise add-ons afterwards.
