Hi, Please can somebody help me. I have recently bought an ex demo C4 VTR+, I love the car apart from the very basic Hi-Fi that comes as standard. On a car quoted as 'alive with technology' I was a little surprised to find that it had no MP3 option ? If I want to change the Citroen offering for something more elaborate will I loose all the steering functionality and hi-fi control?? There are a number of kits but nothing for the C4 that I can find, even the guy at the car audio shop was left scratching his head. Can somebody help me with regards to cables etc. I will be changing the hi fi to a Sony mex-r5 (more mp3's per disk you understand) Thanks in advance Steve.
