Just curious... I was on a ride yesterday, and my 830 froze for about 3 minutes. I knew where I was going, so I didn't freak out and restart, or hard restart the device. 3 minutes later, it unfroze. Is this typical? What's the longest anyone's has frozen, only to unfreeze later? Are we just being impatient when it's supposedly frozen, in which it's just doing a calculation and now showing us? I've seen the other questions on it freezing, but I'm wondering if some of these are just temporary freezes.
