In-Dash Navigation versus OnStar Navigation

GMCSierra4x4 · January 24, 2016

Does anyone know if OnStar Navigation uses the GM map database for routing installations? I saw an option to download MapQuest directions too. I am trying to decide if it is worth updating the GMC software if OnStar subscription is maintained. Thanks.

With the Onstar you only get turn by turn directions. I like to see the map so I upgraded.

So.. are you saying that the OnStar turn-by-turn may not match the OEM map set?

I don't believe it does. If you don't have nav the maps are not installed.

I did the update on my maps prior to a trip I took and the maps where not up to date. I knew I would be going down I49 and it had been over a year since my last trip. They are building this now moving north.

The part I drove on over a year ago wasn't even on the map and this was the latest release... 175.00 for nothing ... Could used google map on my phone instead.

Anyone know if I can get the in dash nav maps installed on my 16' Silverado. I have thee 8" screen but the Navy is only turn by turn. I like seeing the map!!! My 13' Tahoe has the maps and I love it. I want maps on my Silverado.

You'll have to get a module swapped out to do this. Contact MVI on here and they can help you get that.

I think GM sells the OEM stuff as well. I think I saw it on their accessory site.

The Onstar nav is a joke. Not only is it the most basic you can get, but you have to call Onstar and someone has to look up the address. Mine doesn't have the in-dash nav but I'm fine with that since my phone is just as good as a separate GPS like Garmin or Tom Tom.
