I am new to this news group and so I apologize if someone has already asked
this. I am interested in changing out my stock CD player with something that
plays MP3 CDs. I am not interested in FM transmitters or plugins for MP3
players. I had stopped by Best Buy but most MP3 car audio players had knobs
which would interfere with the lid which goes over the stock CD player.
Does anyone have experience changing out their 540i CD players?
