On the first day (approx. 350 km), MRA crashed about five times. After each crash, MRA could be restarted on CP, and all instructions were available, but no map was displayed.

On the second day (approx. 250 km), there were no crashes!

On the third day (approx. 300 km), it crashed twice. After each crash, CP had to be disconnected, and MRA had to be completely restarted on my phone.

The gas station display seems to operate on a random number generator. Gas stations were often displayed, but disappeared just before I reached them. Many gas stations weren't displayed at all.

Another thing I noticed was that the altitude display and the next waypoint indicator often flickered.

I was able to thoroughly test the altitude display in the Dolomites. It was always accurate!
