In my 2007 SRI Vectra C I have the standard CD30 - which is fine. But I would like a unit that plays MP3 CDs, or an auto-changer unit so as to reduce the number of CDs knockin about in my car.

Can anyone tell me which standard Vectra C units I should consider and, if possible, how much I could expect to pay for one second hand?

Any suggestions on where to source would also be welcomed with a large, New Year hug too!... thanks.
