----------------------------------------------------
Habe die neue firmware/software ohne Probleme installiert.
Autobahnen können jetzt ausgeschlossen werden!
Wichtig: Mache einen backup von deine eigene Routes, Waypoints u.s.w. den nach den Update is das Navi wieder im ersten Neuzustand, auch deutsche Sprache, motorrad, lautstarke, u.s.w. müssen neu eingestellt wern. Geht aber recht schnell, wenn man alles ruhig abarbeitet.
Zum schluss muss auch das BlueTooth-telefon und bei mir auch noch das BlueTooth-Dongle von Autocom, angemelded werden.
Auch das ging prima.
Danach sieht man diese Info am Navibildschirm:
