Is there any mod you can do to the stock stereo to play mp3 wma cd's on a g?

 

was yours slavage? cuz mine does that already

 

im pretty sure that all cd playersplay wma and mp3 atleast mine does for sure so that means all the BOSE systems should be able to do it, also i have seen the mp3 and wma run on the stock systems as well... maybe wrong ofrmat or a bad cd?

 

I KNOW the in dash CD changer can play it, and those with nav, the single disc CD player can play it. But for those with nav, the in trunk CD changer won't...... I'm not to sure what the base model has, b/c it isn't a bose system....
