Hi
I need help on bluetooth.

I recently purchased 2005 x5 and I think it already does come with a sanp in adapter. Is this compatiable with any phones? or just certain types? Do I need to get another adapter depends on the phone type?

My current phone isn't bluetooth so I am shopping for a new phone.
Any recommendation? I been wanting to get a PDA (samsung) but I don't think it's compatible with bmw.

Please help

Thank you
