To make it shorter, here's the list:
1) incident detection is far too sensitive, even stopping at crossroads turns it on which is pretty annoying. Doesn't the system recognize changes from a tilt sensor?
2) navigation sounds and direction announcements stop after faulty incident detection was reset
3) they both (sounds and voice from smartphone) work again after the route was recalculated (because of a missed turn for example) ... but ...
4) after recalculating the announcements started with first turn of the route, not the current position (quite confusing)
5) varia vision still is not updated and navigation in meters is wrong (2m instead if 200 meters, 1m instead of 100m), sharp bend warnings do not disappear from it automatically, instead I have to swipe them away
6) edge still shuts down when having live track switched on and a route may recalculate (not always but still does)
7) varia vision sometimes shows no values and I found out it depends on the order the devices are being switched on. if 1030 is on for a while and I switch on varia vision, there are no values being displayed. if varia vision is on and I switch on 1030 after it, the 1030 sends values correctly
