I'm pretty sure it's not compatible with MP3's as IIRC the 'improved' MY05 on SatNav unit has a built in MP3 function..??? I recall seeing mention of this in the info on the revised unit in the 05 accessorries brochure.
I have no idea about windows media, I suspect not though.
I'm afraid you can't swop the unit out for anything else.
Yes, thought it might be like that. Argh, all these small bits - now regret I did not get the 05 and estate. Mind you, thought my Oct 04 was a MY05 uhh... Well, I'll keep the car for a year and get the MY05 estate if I only could keep that a secret for my other half :lol: somehow. Dear, our saloon got stretched in the car wash the other day...
