I got to the point where it became almost impossible to do anything serious with this device because it freezes and restarts when performing the most basic commands just like that. For example, on below video you can seele that simple task as editing galance cause restart and after reboot touch stop to respond... Again this is just a example, there are number of bugs that I am facing with and that I reported all over the forum
I'll try resetting it to factory settings and starting over, but the idea of having to reset the device every few weeks to keep it working properly isn't exactly an appealing option.
Dear GARMIN if U need a serious and reliable beta tester before releasing new products, get in touch with me, no kidding
