I had a problem with the bluetooth interface on my 2006 Le Mans, i took it back to BMW for fixing which they did, but when i picked it up from them i had the DSP option on my menu screen, which had not been there previous to their 'repair' to the phone interface, and when i clicked on it i got the graphic equaliser and side menu, it was there for about 10 minutes and then disappeared.
As i bought the car second hand i am not sure whether this is a glitch or whether it should be on all the time. I bought it from the dealer but don't want to make a pratt of myself by asking them to 'repair' it if its not fitted and was only a 'screen', rather than an active feature maybe someone could guide me on what i can do to determine whether it should be working full time. Someone has said that it would have woofer speakers somewhere in the back, but i have looked behind the panels at either side and nothing doing, are they fitted over the wheel arch or somewhere else. It is a UK spec R/H drive model.
AM I WASTING MY TIME, DOES IT SOUND SO MUCH BETTER WITH DSP ??
