First post. Just bought a used 2008 Titan Pro-4X quad cab last week. Been having some trouble with the Nav system.
When I got the truck from Carmax, the factory DVD was all scratched up so the Nav system was not behaving. I can't seem to get the trip computer fuel mileage feature to work. Also, it was gaving trouble looking up destinations. I also couldn't find the "Vehicle Electronic Systems" option under settings. Anyway The DVD was a few years old and I wanted an up to date DVD so I ordered a brand new one. In the mean time, I figured the trip computer issue and "Vehicle Electronic Settings" issue were not a function of the nav DVD so I went to the Nissan Dealership to have them check it out while I waited for the new DVD to show up in the mail.
Basically, the Nissan service guys said couldn't figure out what was wrong. He said I needed to put "a few tanks of gas through the truck" before the Mileage and Distance to Empty displays would start working. He also said to try the new DVD when it showed up and that should resolve any issues. Sounded like BS to me but I said what the heck.
Well I got home today and and the new DVD was in the mail box. I popped it in and all the navigation features seem to be working just fine. I still have a problem with the trip computer though. It still is not displaying my fuel mileage or distance to empty. Also, I can not find the "Vehicle Electronic Systems" menu under settings. Even with the vehicle runnin in park.
Any ideas what the issue is here? According to my manual my truck should have both options. One isnt there, the other doesn't work. Any ideas?
