I have a 2015 Silverado that I changed the infotainment system out with a 2018 Silverado to have apple car play but android auto does not work and the factory navigation says the maps are missing. I know there was a USB update that needed to be performed but GM has removed those files and are no longer available. Does anyone have a old copy they would share? The VIN to the donor truck is 1GC1KWEY7JF289019 I'm pretty sure the USB update has the maps on it. I'm also in North America. Thanks

I'm seeking this file too, so that I can place it in the download section.

If nobody post it in the next couple of days I'll call tech support and see if I can talk them into sending it to me.

What is the HW number?

Its 84331772 but really i'll try files from any io6 system that has carplay and android auto lol

Update... customer is an idiot and got a non-nav HMI.... I ordered the correct HMI and will attempt the USB update then to see if it has the map files.

maybe not an idiot, why pay for ~7 years old maps if you have android/carplay
