Smartdrive 66 - good concept. Poor execution. My unit is about 3 weeks old. I drive for a food delivery company. I use the 66 about 8 hours a day. Every second day it freezes after a few hours of use. The power button does nothing. Unplugging it does nothing. It remains on in a frozen state in perpetuity. The only option to unfreeze it is to literally freeze it. I have to put the stupid thing in the freezer for 15 minutes. Not very handy if you happen to be on a cross country trip for instance, and the idiot device freezes and leaves you lost in unfamiliar territory. Downright dangerous in some cases. Unfortunately, the Garmin advertising doesn't state that this device is unreliable as well as being expensive. On the plus side - if you never use it - it will never freeze.
