Apologies but im a total noob here... I have just bought myself a w203 c32 amg and wanted to be able to play music via bluetooth in my car! From what I have read and understood I have the comand 2.0 HU and I know it is possible to get a bluetooth module that replaces the AUX in the glovebox, however am I right in thinking that only the volume buttons on the steering wheel controls would work? Not buttons like skip track etc? I thought it'd be ideal if there was a bluetooth module that could just be swapped in for the CD changer? because then the next track buttons would be more likely to work right? or is there anything that can be changed for the cd changer, like an ipod connection or something? thank you guys for helping me out!
