WMA + Autochanger recommendations

Hi,

New to the group so apologies if this has been asked before

I'm looking to replace the hi-fi- in my car, and am looking for
recommendations for a decent CD autochanger that is compatible with
WMA files on CR/R, CR/RW 10 disc would be nice, although I suppose in
WMA format thats a heck of a lot of audio, so maybe 6 would do!

Any assistance greatly appreciated, as well as suggestions for a
source (fitted would be nice too!).

I'm in Hampshire, if it makes any difference

Cheers

Brian
