| | E46 Business CD Head Unit
I have an '01 330i. I was given a '05 325i as a loaner on a recent service trip and notices that I can cycle through all of the FM preset station blocks (1, 2, A) when using the steering wheel control. With my '01, I have to manually switch between the preset blocks using the radio FM button, and can only scroll between the presets in a single block using the steering wheel control. Is there a setting I can change on the head unit to make it operate like the '05?
