General Standard headunits

[stumac1985]

I have a multijet active and have just replaced the headunit as the cd mechanism broke in the original. I bout one off ebay and its one of the ones that play MP3 so is I believe out of the dynamic?

Other than playing MP3 whats the difference?

But it must still be under warranty surely? Why pay for one yourself unless you`r upgrading to a better set?( Not difficult!)
