When stationary in traffic, the position of the cursor/vehicle jumps around on the Tomtom Mobile. This causes the app to reroute constantly - very irritating! Other apps such as Waze and Google Maps (driving mode) do not have this problem. This means the Tomtom app doesn't intelligently correct/ignore bad GPS signals like other apps do.
This is the only issue that stops me from using Tomtom for my daily commute.
Tomtom Mobile developers should fix this.
