Building a Route using the Chevrolet GPS

Hello, I have a 2017 Chevrolet Silverado with an in-house GPS.
I would like to build a route in it from South Central Florida to the Canadian Maritimes a distance of 2000 Miles with about 25 Waypoints.

These waypoints include 11 Fuel Points, four Overnights and several highway changes.

I have a Garmin GPS and always build my routes using my Computer and download it into my Garmin, this works nicely. Think I should use the In-House GPS since I paid for it as an option when buying the vehicle.

Is there any easy way to do this using a USB Stick and put in the Lats and Longs and download it and somehow create the route? Has anyone on here ever did this on the GM GPS?
Any help is greatly appreciated.....Thanks!

    Thanks ktmrfs, that was my backup plan if I cannot do the info in the manual re Lats/Lngs, as long as the online help will give me the vias as I want them like fuel stops, Overnights & changing the highways as desired.
    Your suggestion is a great one and I will see if the call center can do that and I will report back.
    Thanks to everyone that answered and I agree with several.

    My idea of a great GPS is I want to build the route on my 17" laptop and download it into the on-board GPS but that is not going to happen since GM has had years to do it.


    My ideal would be to (a) get MS to revive streets and trips and (b) create the route on streets and trips and (c) upload to the GM nav for the GM route guidance.

    BTW we have on 3 occasion run into a HUGE traffic stop due to accidents. in all 3 cases I called onstar and they were able to give me accident status, expected wait times, and then when I told them we were pulling a 35ft trailer they were able to download a reroute around the accident in two case on a route that was trailer friendly. On the 3rd occasion, I knew the road, I90 over lookout pass, accident completely blocking both lanes. we were on the montana side, and from where we were there is basically NO reasonable reroute. traffic was stopped for 25 miles so we were able to get off at an exit just as traffic stopped. But they did give an estimate of when the traffic would be moving, called at that time, they gave me an update that the traffic jam was now ONLY for 10 miles but moving. So we gave it another half hour. much better than being stuck in a 25 mile string of stopped cars.

  • my 2015 manual has information on uploading and using other gps routes to the nav unit.

    What I have found extremely useful is to just call onstar and tell them the route you want to take and they will download it to the car. As an example we wanted to follow highway 1 as much as possible or 101 where it joined from san diego to cresent city. took onstar gal about 2 minutes to get it downloaded. And the directions on turns etc. through conjested areas was way better than my garmin or google maps had.

    you could probably do the call onstar each day with the route you want including identifying the major roads and they will likely download it for you each day.

    I will agree that the POI's may not be as current as garmin, but the map display and turn by turn directions are way better than any of my current garmins are, including the RV760.
  • I have the navigator in the Mazda and I consider it a toy, useful while driving a new city for checking cross streets as I drive up to them but that's about all.
    I will never give up my Garmin for true navigation.
  • It's likely that paying extra for a built-in GPS will turn out to be a waste of money. I suggest you use your Garmin (or Google Maps/WAZE).
  • Use your Garmin GPS. I have had the unfortunate experience of owning three GM nav units included in my vehicles and they are the most overpriced, worthless piece of junk ever dumped onto their unsuspecting customers. I have experienced missing main roads that were on my Garmins two years before that were still not on the GM 'updates' that I paid for 2 years later. The integrated GPS is a great idea that when integrated by GM will not stand up to a phone app.
  • Sounds complicated to me, we used to do the same thing until we broke up our trip on gps. We knew what roads we wanted to take so we just selected a small town on the route we wanted, selected state, city and then Main Street or whatever showed up in menu for that particular town. So as soon as we got close we canceled that trip and repeated the same scenario on the next town. That way we can be choosy and not worry about where gps may lead us. We have been doing that for many years now with no worry about waypoints and the rest of aggravating things that gps things do. Just my 2 cents and good luck.
  • I have a 2016 Equinox with the OEM GPS unit and found it to be almost useless. Other than point A to point B it's worthless and has the most out of date POI file I've seen on any OEM GPS and yes I updated mine to the latest version.
