With the old software it was no use. I had already tried last year. Have the Navi with current software now about 1500 km use. Route calculation might go a little faster. However, when choosing "winding road" just needs to be calculated as in "car fast" or "Mottorad Directions"! With road closures you should just stay until the new route is calculated, then all is not a problem. I had 2x on the last tour. Tour about 250 km on winding roads, calculating about 20 sec. Have additionally the pilot Moto Bluetooth Headset, works just fine. Direct purchases on Baros. Topic Service: Unfortunately, I had a device with a screen damage. Have the Service (Baros) called, sent there on Monday and on Thursday device I had back a new device. You must call at Baros, not at Blaupunkt :(
