Yesterday I fitted a parrot ck3100 bluetooth carkit to my 2005 A4 saloon. I have read loads of stuff about it being difficult because of the BOSE etc but I just thought it through and installation was straightforward (about 3 hours).

1. Bought a ck3100 from FoneJunkie for £89.99 including delivery

2. Bought a set of crimpers from Maplin.

3. I could not use any of the connectors on the Parrot loom because although they are both ISO, Audi uses a larger connector for some reason. However you do use the separate brown and green wires hanging off the loom. They connect to the speaker line in on the back of the Concert II stereo. You also need to cut the bullet connector off the yellow mute cable and connect that to the mute connector. I just used 3 shielded small spade connectors and plugged them directly into the pins within the ISO block. I found the diagram (see link). On mine the block with the tel +/- and mute was unused (because of the BOSE) and that is where I plugged the spade connectors.

4. I then flipped off the fuse cover (end of dashboard next to door) and then removed the 3 bolts which hold the underside of the dash in place to reveal all the wiring. From here I could access the back of the fuse box and located an ignition and permanent feed for the kit. There are plenty of bolts to take an earth from.

5. For the microphone, I flipped off the lighting cover in the ceiling and then removed the 2 screws. The entire housing will drop down allowing you to feed the microphone through. The wire can be tucked in all the way round the windscreen until you reach the fuses.

Thats it really. 6 wires in total, and I did not need to buy any additional leads. Nor did I need to damage the wiring on my Audi. I am very pleased with the results too!
