Hi, When driving Rider 550 screen goes blank and after a few seconds come back to normal driving screen. Screen looks exactly the same, just positioning triangle has been moved under speed and road name window at the bottom of the screen. After next blank-life cycle, positioning triangle moves back where it should be. The faulty unit has been replaced by Tom Tom to the new one, and new one does exactly the same trick. I updated both units to the latest software. First unit has been restored to the original software after fault was discovered, but fault was still there.
The unit connected to the Samsung phone via bluetooth and running of the battery power while on the motorcycle.
Noticed, that when unit in my car it was performing faultlessly (again running from its own battery). This weekend going to Prague in my own car. Will be a good time to test it again.
