I have a garmin 810 that i never really use. I had to use it while in hawaii to show me where to go. it crashed every time i used it, and the live track feature would bug out within miles. Garmin's have too many useless features, and too many necessary features that don't work (ask anyone who owns a garmin own many files they've lost). Overall, if i was looking to buy a garmin i would go with a 500, they worked a lot better, and right now it's software has been finalized and "perfected". However, my pc7 is a heck of a lot better.
