Hi all, I've recently purchased a 2010 Audi A3 sport tdi. It has the audi concert system, how easy is it to install the Audi navigation plus, is it an easy plug in or would I need it coded. Also on th navigation plus, it has Tel button, does this have a built in mic and Bluetooth I've attached a photo of the original system and the one I'm looking at Thanks
