Thought I'd pass this info on...

I called "GM Nav Disc" office about purchasing a new Nav Disc for my navagation system. I've got version 1.0. They told me that version 4.0 will be out sometime between June and August of this year.

I asked the question - If I buy the current version 3.0 now, will I get version 4.0 free when it comes out 2-3 months later? Answer - NO.

Obviously, I'm waiting until 4.0.

 

How much do those disc cost anyway?

 

Cost is $199.00

 

Has anyone compared the detail contained in the GM nav disc with the detail Garmin provides or other aftermarket navs such as the Pioneer? Some of you might have an Accura with the nav as well as a Corvette with the nav.
