TomTom Rider 550 - Black Screen
My TomTom 550 - less than to years has know to times gone black while navigating. Subsequently, it is not possible to restart the device. The first time it took 3 days before it suddenly started up again and this time 6 days. I can of course send it for repair, but fear to be told nothing is wrong, now that it has come to life again. Others who have had a similar problem and know how to fix it?
