Best options for XM
I've got an 08' M3 so from what I read it is the CIC unit..
Anybody have XM in their 08' after doing either a external unit purchased from XM or maybe done some coding? I really want XM but I don't mind having an external unit.. but if I can get coding done and some hardware for the same price, I'd go with that.
