I recently upgraded my dash cam from an old Mini805 to a Garmin mini 2, expecting (quite reasonably) that this would be a significant improvement. I'm really quite disappointed in the Garmin. The video quality is not as good as the Mini805, the bluetooth and wifi performance is awful, and it costs a lot more than the old Mini 805.
Bottom line - don't replace your Mini805 with the Garmin mini 2 or you will be very disappointed!
