Does someone have a link? It is very important  |
The correct way is to code the navigation so that INFO and SELECT work
The reason they do not work is that the BM23 radio module fitted in the car is not the same as the radio module set in the navigation computer. Navigation expects to see a BM54 radio, but you have BM23.
(BM54 is the default setting)
So you need to change WIDESCREEN MODE to reflect the correct radio
Because this setting is wrong, it is highly likely that the other nav settings (VIN, vehicle type, etc) are also wrong
You can correct all of this through either recoding at a BMW dealer, or by using my NavCoder software.
You could ask on this forum or on some German forums for a BMW fan with NavCoder in your area to recode for you.
