Hello all, quite interesting discussion here. I gave up with Android devices and navigation and changed to XT3. So far very happy for my use. I plan routes with the MRA route planner and use GPX 1.2. So far no issues with changes of the planned route. Garmin is just sitting above the dash and it's there. No hazzle with offline or online maps. No overheating of the phone if using CarPlay and no battery drain of the iPhone. I had several issues during my last rides with outdoor phones and tablets and found MY, maybe a bit old school, solution. The screen of the XT3 is great and serves my requirements. However MRA-App is a great software but a Garmin is a navigation system and a phone is a phone :).
