Regarding the “Change the Speed Sensitive Volume Ratio - E46 Business CD Head Unit:”
I currently have a 1999 323i.. I tried putting this feature in the car, but it seems not to work.
Do you need to have the car on? Running? Or parked?
I get up to the part of “Gal” and I press the #’s 1-6, but what else do you do?
I just pressed a number I put it in #3 and turned off the radio. I turned the radio on once again, took it for a drive, but the volume did not increase.
If any one could give me back some feedback.. I would appreciate it.
