FWIW, my SO bought a BMW w/o Nav & after seeing my Camry Nav system bought a Garmin 660. Very Impressive! Doesn't refuse to give guidance in the foothills where we live, portable, built in Bluetooth, etc. I actually like the Nav piece better than the Camrys.

Apparently the 300 series is the same without Bluetooth for much less $$.

On the other hand, she left it on the dash while parking overnite in San Francisco and came back to find a smashed window and no Nav. Thank goodness for the AMEX coverage.
