Is there an issue with bluetooth on the rider 550? For 2 weeks I have a new tomtom 550 but it connects with bluetooth whenever it likes to do. Mostly not when I want it to. Solution is switching it off and on as long as it takes to connect to mydrive and headset. It never happens like it used to with the rider 410 or 450. It's allway a struggle to get them connected, one or both. Does someone knows the solution to get it connected like it has to and how it's used to be with earlier models?
