GPS problem on a 2008 Model

[bacano_2006]

I just bought a 2008 Suburban. The GPS works some of the time, but then other times it has some issues:

1. I was coming from Texas to Florida. I set the map to Florida. When I hit "Go" for the directions the map became disorientated, or rather, the arrow on the map was no where near where I was and it was following its own path.

2. Now when I put the map on it does the same thing. Sometimes it is correct and follows the path I am on, but other times it is way off and seemly roaming like an escaped drunken goat.

I am curious if there is a way to calibrate the GPS or reset it or give it a good talking to. Also if there is a previous thread on this please lead me to it. I wasn't able to find one on point.

Any thoughts?

Sincerely,
Almost lost.

You may need to update the mapping data.

And is that done with an updated disk. I'm guessing that is the case but I am new to the newer model. I had a 2006 Tahoe. I tried to eject a disk out of this truck, but there doesn't appear to be a disk like in the Tahoe that had to have a disk to function.

Your 2006 disk would not work in the 2008 anyways, with some Google-fu you can find what you're looking for as far as an updated disc for your specific vehicle.
