Replacement disc for GPS on 2007 GMC Yukon

I am trying to find out where I can get a replacement/updated GPS disc for my truck? The one I have in there now is the original.


Dealer. Be prepared for sticker shock. I get “reminders” to buy a new disc for my '05 Pacifica every year. Cost is “only” $200. Not worth it, IMHO.

Why do you want to update so soon?

Crapload of new construction in my area (Phoenix) and my wife could not point north on a bet (it’s her car)…


Time to install a Boy Scout in the luggage area!

But I know what you mean about construction. However I always find it a little amusing when my nav system thinks I’m driving through a field or pond when I’m on a road it doesn’t know about.

Yeah, that get’s a little creepy when it tells you to take a left when you are on a new section of highway…

Many cellphones now have navigation built into them and are updated by the company. For the cost of one year’s new nav disc you could get a new cellphone and always have up-to-date navigation and phone to call if there was an emergency.
