Navigation Won't Run
 

Just bought our 2005 GX 470 and love it but the navigation will not work and effects the maintenance tab also.
Have the original nav map and purchased the newest update. Neither will work?
I have tried all of the reboot options including battery disconnect.

It just says "Insert the correct map disk" and it has a bunch of Japanese gibberish under it?

Don't care about the vavigation but want to access the maintenance dashboard?
