Having lived in Hawaii, I just have to ask. Do you get lost easily? Living on the Island, a GPS is last thing I would need or want to waste money on. I can understand the Bluetooth and other options but GPS? Do a Google sear on Mac-Prius or Mac- Mini Prius and you will find what you are looking for. By the way, the GPS Nav system is a $5000-$6000 option. That's a lot to pay in itself but to pay that for living on an Island where you would seldom use it if at all. A Garman can be had for $300-400 and is portable. By the way, the GPS is DVD based.
