I read online that pulling the raido1 fuse and putting it back in can sometimes reset the nav system if the disk wont read. Only problem is I dont see a radio1 fuse anywhere in the car. Any ideas??
Fuse #28 in the engine compartment fuse box. See owner's manual, p. 465. Oops, my bad. Above only applies to Gen III.
It appears that there are 2 fuses to look at. Dome fuse that is supplied by the 12 V battery; and ACC fuse that is supplied via the ACC relay. Location of fuses: I have attached trouble shooting info for the Radio Receiver Power Source Circuit. Hope that helps.
