Just bought a 2001 GLE for my wife and the BOSE head unit works fine other than you have to push down on the volume **** and turn to adjust the volume and the steering wheel controls don't work at all. Anyone experiencing the same issue or know of any solutions? Thanks in advance

 

my 2000 gle has same problem, looking for answers

 

I have the same problem.....I stopped using the headunit **** completely and kept trying wheel controls, eventually they started working and that's all I use now.
