Hi all, First post for me on these forums and I'd like to start with a quick question! I'm about to pick up a 2005 A3 which I believe has the concert II single DIN player in it. In my current car (a 2004 Polo) I have one of these installed and I will be wanting to switch this over to the Audi. Kenwood Electronics UK Ltd. | USB Receivers > KDC-W4544U (details) Is it possible from looking at the spec for this stereo to tell me whether it will be a simple process? I've read all kinds of things about harnesses, wires to the ignition, adapters and the like, and I'm not the most experienced when it comes to I.C.E. All I want is the ability to play MP3s off a USB stick, if this stereo wont work (or you're not sure without seeing the connectors on the back of it) what other cost effective ways are there for me to do this? Thank you very much!
