Does anyone have any info on how to upgrade the nav system from the Onstar turn by turn one to the display that actually looks like a map? I talked to the dealer and they said around $2,000 to add a module..

I'm taking it you want to add the My link nave system into your truck? If so....
It's expensive but can be done....
Here's one thread..I believe there are others on that same site...silveradosierra.com

Thanks.. I've done a bit of looking this morning, and have came to the conclusion our smart phones will work...

If you have the model with buckets and full console there is a slot for a tablet....
I use a tablet, loaded with TOPO maps, for backcountry driving that the MyLink navigation system does not show

There's an Android app called HERE. You can download the maps that you need. That way there is no need for a data connection. I use it all the time now, works great. Also have a bracket from Amazon that holds my phone and clips onto the air vent. Very useful when I have to travel and rent a car.

I don't understand. I've been using Garmins for years and they are better and more functional than anything the car manufacturers install.
