Has anyone here had problems with their factory installed NAV on the 2003? Started to do a search but am not finding anything. Mine has not been able to read the DVD a few times but when I restart vehicle it works just fine. Have also had greyed out buttons not become workable again when vehicle was at a stop. The other day NAV would not respond to me touching the "Home" button. Had to do so several times to get it to work. Have also been having audio problems with loss of volume and have read through a few threads on this. Just curious to see if others are having problems with NAV and what, if anything, has been done to resolve problems.
Thanks.
Thanks.
