My last tripwith 4.1.2 (305) wasn't good as well.
Also strange autoskip behavior.
On my route i went through 2 very short tunnels (10-20 meters long). Directly behind these tunnels was a shaping point. Due to these tunnels. The GPS signals was disrupted shortly. Shown as a straight line in the tracklog. Both shaping points were on these straight lines.
Both shaping points were not seen as "visited/reached" and there were also not auto skipped (i have auto skip enabled). Other shaping points were autoskipped. Not these 2.
First i had my "Waypoint Notifications" set to All. This was a disaster.
I missed a lot direction announcements. A lot of shaping points were annoumced as next waypoint (in Dutch: Aankomend Routepunt). It was very quiet in my helmet from time to time.
Autoskip did not work proper also.
After i change the setting for "Waypoint Notifications" to "Via". Everything was much better. Normal direction announcements and kind of normal autoskip functionality.
But the level of stability i experienced with version 4.1.0 (AA and ACP revamp) is not there anymore.
This version is not good enough.
My wife begged me to go back to TomTom Go. According to her I am much more pleasant guy when riding with TomTom Go.
