Pioneer has plenty of Premier series HUs with BT built in now. If you want a full-fledged DDin Nav, maybe an DNX8120? The Pioneer 90 will be out pretty soon, and that's what I've got locked in my sights at the moment.
if you can find a eclipse 8443 jump on it //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif hahaha i personally like pioneer premier lines
I recently used the CD3200's bluetooth, and I thought it worked well. I personally have the Kenwood 8019 double din nav, and the bluetooth is the best I've heard.
