Navigation Device Unavailable
Anyone know how to fix this? When I push the NAV button it says : Navigation Device unavailable. Was working fine yesterday and now this...
or is it something I HAVE to take it to the dealer for to have fixed, have warranty but can't stand wasting the time there.
Thanks,
Ray

Try extracting and then re-inserting the DVD Navigational Disc, to see what happens before you have to take it in. Just my .02 cents It just might work.

you may need to have your nav processor replaced. i went through the same deal. eventually, the nav drive took a dump and would not read or eject the nav disk. there is a TSB on this. i'll look it up and post it.
