Noticed a couple navigation app bugs recently. Wondering if anyone else has seen it and how to correct it. 1. Turn-by-turn audio gets stuck - sounds like a skipping record. Ended up having to put her on mute. Fixed itself the next time I had to use route guidance. 2. Highlighting of the current route is corrupted on the 17" display. Instead of a solid blue line indicating my route, I will see mostly no highlighting except for small bits of blue every once in awhile. The heads up display on the dash screen shows the highlighting correctly. This one seems to be persistent - missing every time I use the route guidance.
