Don't start the update with headlights ON!!!ĥ) Press and hold MENU button for cca. (Use a reliable and error-free flash drive!)ģ) Switch OFF all consumers (lamps, aircon, aux/seat heating, etc.). Mac is not a good idea for this as it puts loads of trash on the card and you will have problems.ġ) Copy the archive to your SD card/USB stick (formatted to FAT32 filesystem), 3 folders and metainfo.txt goes to the root directory Use a Windows PC to copy the archive to your removable media. To avoid battery problems you have to options: 1) use a battery charger 2) do it with running engine (tested and works). Update date/time/version will remain visible in the HU's service menu. If you don't want to get 'questions', it's better to clear those fault codes. If you don't clear them, your dealer will see themĭuring next service. Please note that updating will generate fault codes and these are stored in your car. VCDS coding can be ignored and the HU will still work without problems or warning messages. Note your current setting, it's under MENU/Setup/Screen/Brightness. Your menu settings will not be changed except the touchscreen brightness level (which will be set to 'Darkest'). This may result in interrupted update and a bricked headunit!!! Your car has a battery managament system which is able to switch OFF ignition when the battery voltage drops too low. You need a properly charged car battery for a successful update (it's done with ignition ON).

improved reversing camera screen (for retrofitters, "transparent background" and auto-hiding picture control buttons) better sound (probably only with Canton) Main advantages of a new FW (depending on your current version): Basically it is designed to fix issues in previous versions. Updating your HU firmware will not add new functions (MirrorLink, etc.). The procedure is quite simple and safe but there is always some risk of damaging the headunit if something goes wrong. This FW update is suitable only for MIB1 (1st generation) Bolero and Amundsen headunits. This video is about latest MIB_I software update to version 0490
