An advantage I see the route planning on the PC in conjunction with the free program from the network ([...]). This tour can be in the whole of Europe (perhaps more, have not yet tried this) create and upload them without problem to Navie's. In NavGear on the file (xxx.kml 4.2) and then just go. The first way - point should not necessarily be the Sons and daughters standpoint but a few meters further along the tour route, otherwise the Navi will always start the first point that bothers perhaps, but can easily tap three times (Routes change) will be deleted , With the "Moto Planner" program can also be easily GPS files from the planned tour to create and send via the URL address to be created for other acquaintances via the Internet by email with the link. A print of the tour is also possible and suitable for the tank bag.
The Navie work / also shows approximately constant speed in the tunnel on the expected curves, especially in Italy quite helpful.
Very wide range of accessories. Good mounting the BT receiver is in the various helmets not quite so simple, however,
I think I can do that inexpensive motorcycle Navi "NavGear SLX 350 Pearl" recommend.
