I contacted Garmin who politely explained that my nav unit is defective based on what I'm experiencing and needs to be returned so this unit is going back to Best Buy on Saturday. Or Sunday. Something about the internal memory being corrupted.
I've had my local Kenwood dealer order me a DNX573S which should hopefully solve my problems.
In the end, this should be okay. The more I'd read on the DNX572BH, the more I didn't want it anyway.
