FYI. I own a Model II with the standard radio. I have discovered (I think) that the Garmin voice recognition feature will allow you to make hands free calls through the HU while underway. This is very handy, as the factory radio goes into lock out mode as soon as the car gets underway. When you activate the voice recognition on the Garmin the "Hands Free" icon pops up on the factory radio. Just push and talk. This might not be a revalation to some but it was to me.
