Sounds like your nav unit dvd player may be on the fritz, but easy enough to check and replace however but expensive if you are not under warranty. There are 3 wires which plug into the back of the unit all with unique plug connectors...slide your drivers seat forward, disconnect all the wires, remove the 4 small bolts holding it to the frame and test a new unit (at the dealership or if you have a friend with an RRS. If it works, you've found the problem, if not, you may have some chafed wires at the loom there under the seat.Tarantino013 said:It worked!! thank you
Now the only problem I still have is: on my screen is written: "nav not available". Everything else is working like my start up screen and the 4*4 display.
only my nav is not working , i allready changed the disc buth no result.
