I've got a 2018 3500HD D/A. Just got an email with an offer to upgrade my GPS maps for $99.99, supposedly a $60 saving. Is there a cheaper way to get this done or do I have to bite the bullet if I wanna upgrade the maps?

Mine is a '15 and I think I bought the map update last year for the same, $99. Not sure if it's worth it for one year. Your call.

Android Auto or CarPlay will let you run current maps from your phone -- instead of the trucks nav -- for no extra cost.

Thanks all for the info and ideas. Just gripes me to have to pay that kind of money for a crummy gps map update after shelling out the $$$$$$$$$$$$$$ for the truck.

GM doesn't make the maps. They buy TomTom or Navionics or some other nav supplier. What GM charges is probably a pass through charge with a markup.

As redwngr posted, just use Android Auto or CarPlay. Your phone has better maps and it's free except for carrier data charges.

My 2020 gmc maps are junk. Took me to the wrong location the other day. I had to end up using my phones google maps to get to where I was going.

Kind of like the GPS on Harleys … the whole system is junk IMO

This is a shot of the new CarPlay with iOS 13. Apple updated their map app so it's pretty decent now. My go-to is still Waze. There is good functioning with maps, phone, texts and music apps. I like the new CarPlay.

Note. The song shown is Jason Boland's Telephone Romeo. That is not Jason Boland calling me. :wink2:

I'm wondering the same thing. I really like the truck nav system and have found it to work well. Looked on ebay but did not see latest update. Seems like something you could buy and resell for a few $$$ less and keep passing it on.

OK...I just ordered it. I will update the post once I install it. I will sell it on eBay to recoup some of the cost. Whoever buys it could do the same and so on. Thanks.

I hope Waze can show in that screen soon, Carplay is the way to go. Has traffic, up to date info, etc, etc, etc...

I am also not at all impressed with the GMC GPS system. Wrong direction, inability to locate significant towns, missing roads that have been in existence for years. I have used a separate Garmin or just my phone.

When we travel & have to rent a car we normally take our Garmin since the rental car is cheaper if you don't get one w/navigation. Well, we just got back from a trip where we took the Garmin to use. Rental car didn't have any built in nav as expected, but it also didn't have a 12v plug in the Garmin could use (i.e. no cigarette lighter receptacle)!! First time I've seen that in any car (our rental was a 2019 Buick Enclave). The rental did have a carplay app so we used that & all was good.
