Just bought a new Enclave. Is it possible to add navigation without having to go through On Star? I bought a Dodge Ram and was able to add Navigation through the internet.
I don't see anywhere in the manual that says you can. Thanks for any replies.

 

I was able to add navigation from the company that supplies navigation to the 3 auto makers. cost was about $400.00. Did the install and it works great. Took about 10 minutes.
