Source Mode memory
 

One annoying feature of my new X5 is the lack of source mode memory... I think that's what it is called that recalls tone and volume for each source mode e.g FM, CD .. this is a common feature on car stereos and I thought BMW would have had it... it's annoying to switch from CD to FM and to get blasted due to the volume difference.. is this common in BMW's not to have this feature?
