I have a bluetooth/nav/etc built in to my car - the Nissan Altima. I've used it with my AT&T Blackberry Bold 9000 for about a year and a half flawlessly. Now I got my Droid X and it pairs up and everything, however, the audio sounds like garbage and the mic part does not work at all. If it were an analog thing I would imagine the mic/speaker were shorted together. I have tried it with and without Enhanced Stereo (the only bluetooth configuration option). This didn't seem to change anything. Thanks in advance for any suggestions! READ THIS EDIT: 9/22/2010 I pulled down Froyo. Just a few minutes ago I paired my phone with my car and am happy to report a working test call. I called 800GOOG411 and heard it just fine, spoke into it to call the office and heard the office recordings perfectly.
