Question about BMW Cars & Trucks
With the key in position 1, if I turn the radio on and hold down the Traffic key I can access the service mode but it only gives me the service serial number B1029238 and software version 29-26 29, the GAL speed sensitive volume control, the DSP digital sound processor which it is not fitted for and the FM field strength for each station. The problem is that the frequency range is set for 90Mhz or less and I need to change it to up to 109Mhz for USA stations. How do I access that function.
Save hours of searching online or wasting money on unnecessary repairs by talking to a 6YA Expert who can help you resolve this issue over the phone in a minute or two.
Best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.
