| not too much info on it, but my mini is also a 2004 and has the factory radio, and also refuses CDs.
i think mine is shorted out, though, because the problem started when my sunroof was left open and it was raining. (not by me, of course)
i'm using it as an excuse to get a new head unit, personally, because i want USB connections and bluetooth, and when the factory bluetooth kit costs more than the head unit i want, which has two USB ports, an aux input and bluetooth all built in, it's just a convenient coincidence that i need a new head unit. |
