I have a Garmin 2820 w Hands Free Bluetooth & a Treo 700w. After install the Garmin works fine, except it does not bring over my speed dials. I know this works because other people where I work have the same units. And alos after power down of the Garmin, I have to select hands free on my Treo to get the Bluetooth to work properly on the Garmin. When it works I love it, but it is a pain to have to constantly have to reset my Treo.
