Today I tested the new version of MRA next (4.3.4-377) with AA on my Chigee AIO-5 for BMW (with latest firmware) connected with Pixel 8 phone with android 15. I also read on this forum about zoom in on your phone for a better view of the directions on the map and clearing the cache when GPS was stuck.
The start of the test was promising. The zoom level was ok, the directions were given correctly. Nice. I planned some stops where I wanted to turn off the engine. After the first stop I started navigation, but the arrow was stuck at the position where I had stopped. After a km of driving the arrow was still on that location. I stopped for clearing the cache and restart MRA. All seemed OK since the arrow was now on the correct and current location. But it didn't move after I started to drive again. I tried it several times, but the behavior was the same. In the end I could still hear the directions and see them on the screen, but the arrow and map remained at the last location. So while the navigation gave the correct instructions the map and arrow didn't move. Also the track that I recorded was only correct at the beginning of the trip and had straight lines between the spots where I cleared the cache.
Conclusion for me: MRA on AA is still not working as I would expect. I hope these issues will be resolved before the new riding season starts, otherwise I think I will start using the TT GO Navigation. I also hope the developers can use my tests and fix this problem, because I definitely would like to use MRA on AA.
