On Wednesday I get my new Citroen C4. In the past I always had a complete system with power amplifier, subwoofer and enough boxes in my car, but this time I would like to do without it because, at least if you want to believe the general reports, the factory radio is not particularly adviceable to expand (operating elements on the steering wheel become pointless, radio infos are no longer displayed in the display of the onboard computer, etc.) I could also live with the factory equipment (k But I’m afraid that normal radio (RD4) will not be able to read MP3 CDs. However, you can find quite repeatable hints on the internet. How is that with your C4’s? – What equipment do you have? – How long have you got the car? – Which radio do you have? (Some also have the RT3) – Does it play MP3? Do you know what it depends on whether the radio can handle the MP3 format? I get a Citroen C4 HDI 110 limousine in the exclusi v-equipment. I’m grateful for information, I’ve been trying to get this info for days and get contradictory messages again and again. Even the car dealer could not help me… You can’t imagine how I’m happy to finally get my C4. At the moment I don’t have a car..
