Audio 20 was Mercedes' standard head unit for a decade: a small screen, a radio and Bluetooth, and no navigation. If you'd like the car to have the equipment it should have had, we can upgrade it in several ways, each coded into the car so it works as a factory option.
Add navigation
Garmin Map Pilot on NTG5 cars turns Audio 20 into a full navigation system with an SD card and a data-record update — the most cost-effective upgrade for most owners.
Larger screen
The 7" or 8.4" screen that came with COMAND replaces the small Audio 20 display, with the same bezel and the same look as a car that was ordered with it.
Full COMAND Online
For owners who want the lot: hard-drive navigation, DAB+, internet services and the full COMAND menu system, using a genuine unit coded to your car.
Mercedes me 3G to 4G
The 3G networks that connected early Mercedes me cars have gone. We fit and code the 4G communication module so remote services and live traffic come back.
Coding is the difference
Anyone can plug in a second-hand COMAND unit; the result is a screen full of errors and a car that misbehaves at its next service. Every unit we fit is coded to the vehicle and the vehicle's data record is updated, so the dealer's tools see a car that was built that way.
Add factory CarPlay and Android Auto at the same time and the two jobs share the labour.
