Navigation update
Don't buy the Nav update promoted by GM. Wife got me the navigation update for my 2014 C7 as a Xmas present.After installing, I checked to see if it would t find my home address. Stated no such address.Turns out the update is as of Aug 2018. Totally useless to me. Yes, install was validated by update number. Not happy. Any way, Happy New Year to all.

Honestly, I like the car NAV but when the doo-doo hits the fan, google maps is my backup. I have NavTool and I can hook my phone up to the NAV screen and google maps is displayed. My 14 didn't have carplay, so I needed to improvise to get the function.

I bought the update for my ‘14 a year ago - made a big difference in how the system performed, especially the time of arrival calculation.
Really surprised that the maps you got were a year and a half old. Maybe contact the supplier and question whether you got the latest version.

yes of course we can use our phones...but that can be a PITA sometimes. It's nice having the big screen and HUD show you the way.

My experience with both Ford and GM nav update online purchases has been abysmal... Both were ridiculously expensive and failed to include major highway changes that had been completed at least a year or two before the "update"...
I have decided to "upgrade" the nav database once every three or so years, and use another source to check the availability of roads...
IMO GM should NEVER have gotten into the nav business since there are great companies that do nothing else and GM sucks at it by comparison....

OP, did the update ask you to put in an address for a Nike store in Detroit at the end of the install? Wondering if you didn’t get the 2020 version.

You do know that Navtool will give you that ability to have your phone display on your NAV screen as well as give you a front camera?

I have taken two long trips in the last year where I wish I had GPS, instead of cell data driven apps like Waze or Google Maps. If you do not have cell data, these apps do not work. In West Texas and again in Arkansas/Missouri I lost service and was without Navi. Less an issue in Texas as I could figure my way, but on the other trip I was truly lost. While I did not order Navi on my 2019 Stingray, it is included in 2LT on my C8 build.

Ahhhhh...very true. I had forgotten about that. Honestly hadn't considered doing that mod. A long time ago it was not worth the cost for me. Looks like it's less now. Hmmmm.

I think you misunderstood what KemahGT was saying. You can download the full map data ahead of time from your home (or any other) internet connection for any area that you might travel to so you do not have to worry about having cell data while on the road. The factory nav is always nice to have as a backup, but simply preloading the maps avoids the worry of losing cell signal when using Google Maps.
Is the download the "route" you plan to take? What if the planned route is jammed or blocked by an accident and you need to do a bypass? Will it recalculate an alternative route for you with the downloaded data?

I just installed the 2020 update in my 2017 Z06 and am glad that I did. The area where I live and its surrounding suburbs are rapidly growing, and new roads are being added all the time.
When I'm just driving locally, I don't want to use my phone for navigation, so I just keep the car nav on the screen. It has already helped me out a few times!
For longer trips I would use Waze, of course, but just zipping around locally? Nah.

No, it isn't just a particular route. You download the "offline maps" in Google Maps by highlighting the regions that you want to download and the entire maps database for that region is then downloaded to your phone. I have 3 regions selected and that covers my entire state as well as adjacent states. You can select and download as many regions as you would like.

I have downloaded trip data on to my phone prior to traveling (having learned the day before the phone is useless unless you prepare the trip in advance), but I have not tried to change the trip en route.
Downloading the data to the phone prior to leaving is a kludgy work around.
I continue to find frustrating that a $150 Garmin easily outperforms the built in nav in the Corvette and every other car nav I have used.

I have had the phone (Android using Google maps) warn me that phone coverage on my planned route is spotty, inquiring if I want to download map data in advance. I have learned to respond "yes."

I travel a good deal. This would require downloading essentially the entire country.

Of course everybody may use whatever form of navigation they wish... this is just to debunk the myth that Google maps is useless without a mobile data connection. Most people aren't travelling cross country very often, so downloading a small region on the map will be sufficient for those people.
