I took the V back in for a 42K mile service, (oil change only so they tell me). While is was in there I complained about the rear differential whining again. I must only have about 5K on the last one. They replaced it no problems. Now I'm on the 500 mile break in, so not fast accellerations.
I also complained about the NAV not letting me select another state. I know it worked before when I traveled to Philadelphia PA. This time I was trying to get to NY City. (Children in the Macy Thanksgiving Day parade). I couldn't program in Englewood, NJ where they were supposed to meet. I printed mapquest directions, so I started off. I took a wrong turn on the way so I stopped to try and get the NAV working. I was on the OnStar for about 30 minutes with Cadillac support, they couldn't seem to help.
I found I95 again and made it there. Now it was night and I took a bunch of turns to get there, I didn't have reverse directions back. I called Cadillac again to help, because I figured I must be pushing something wrong. Well after about 45 minutes of them tell me to tap the screen and me telling them it wasn't a touch screen, they told me it was broken and take it to the dealer.
To finally make it home, I programmed in POI airport, to take me to BWI. First time through it started calculating the route then rebooted. I tried again and it worked. I would need to ride past my house to get to BWI so I had my route. I made it home.
When I complained to the dealer about it they said I needed a new NAV DVD. I was going to buy one anyway but they said it would be covered under the warranty. It hasn't arrived yet but we'll see if it fixes the problem.
