Hi I've just ordered my new Audi A3. Its gonna have the standard concert Hu with Bose. I've been looking at all the various Ipod integration options for my Iphone and am considering a bluetooth phone kit too. For the ipod I've decided upon the Harmon Kardon drive+play so that I can use all my play lists, not just the 1st 5. It uses either a hardwired FM modulator (plugs into the aerial socket on the back of the HU) or the better choice of 2 phono (L/R) plugs at line level. I can make up an adapter for the 2 phono plugs and have seen that the Concert has 2 line level (or are they high level? - not sure) inputs on the back that are also used for a cd-changer. My question is what adaptor / plug to i need to get to plug into the back of the HU and where can I get it from? It doesn't matter what is on the other end of this adapter as I can cut it off and solder on the phone sockets, just the HU end that I need to worry about. Or are these wires already going to be there (I haven't gone for a CD Changer) and I can just tap into these using scotchlocks or something similar. I know that the new Audi's have a 3.5mm input socket so could I tap into that in the same way? The following thread indicates that it can be done: http://www.audi-sport.net/vb/showthread.php?t=47231 Is it still the case that the aux-in need to be enabled by a dealer (or someone with a vag-com) ? If I later go for a bluetooth phone kit such as the parrot or audi what impact does this have on the above installation, or do the bluetooth kits use a separate connections on the back of the HU, if at all? Thanks in advance.
