Have had a RAV4 BJ 2010 with the Navi TNS510 for a few days. Yesterday, after starting the Navi screen, the security note stopped and “show map” could not be selected. Since then, no navigation functions are to be selected or stored. The radio and the telephone function (Bluetooth connection) work perfectly. When querying the SD card the version (10-11 1. WEST) is displayed and also the corresponding area. I have the map lt. Besch I can enter my location or choose a destination but as soon as I press “ok” or “start” nothing happens and no card is displayed. Maybe someone knows this problem and a solution? Have already thought about buying an update but am not sure if it will work. Thanks for your support
