Just wanted to let you guys know that the Kenwood Bluetooth Adaptor has been released and is available at Crutchfield and if you're lucky, local stores.
I got one locally this morning and installed it in about 25 mins.
A couplethings to note:
-If you have the Ipod adaptor you will need to unplug the Ipod adaptor from the back of the headunit and plug the Bluetooth adaptor into the headunit. The Ipod Adaptor then plugs into the Bluetooth adaptor.
-This can be a pain if you try to get both adaptors in the dash. I ran mine to a empty spot under the console.
-The Ipod adaptor works as it normally did without any changes after adding the Bluetooth Adaptor.
Performance- I ran the mic up the a pillar and mounted the mic at the end of the pillar. I'm very impressed with the call quality and incoming calls are displayed immediately on the screen. I havent' had a chance to play with it more but i give it an initial thumbs up for ease of use and call quality. My fiance has the Avic-Z1 with bluetooth in her car and I feel that the sound quality is a little better with the kenwood. BUT I may be a bit biased because my car is cooler than hers.

 

Of course it is, its a Z!
