I'm new to the forum (just bought a used '06 5 last week), and I was wondering if anyone has any useful detailed information on changing the factory single CD player. Maybe I am stupid, but I have been searching the internet high and low the last couple of days and I have not been able to find much in the way of clear, simple, directions or advice in either repairing/replacing the existing single CD system or upgrading to an aftermarket solution. As stated before I am new to this and I am not much of a "car guy". I just (a couple of minutes ago) purchased thishttps://www.amazon.com (commissions earned), did I waste my time and money?
