I have a Renault Megane Coupe (Y Reg) with the traditional steering wheel controlled stereo. I am wondering if I can replace the CD changer to something more modern, for instance a CD changer that reads MP3s or similar, or potentially remove the unit altogether and install a hard drive or similar for music. The reason is would prefer not to change the unit is that the facia is curved and its difficult to find a stereo that matches. I would also like to keep the original equipment steering controls.
