I have a happy update: GM came through and called me with a possible fix. I took them a month but at least it happened. The Dealer had to uninstall ALL the software on the truck and update all the operating systems for the HMI. After that the map installed but disabled the radio so they had to perform a global reset on the truck again. Everything works now. Total labor cost is 323.99 for a 99 dollar map update. I am not going to do this again, lesson learned.

I think I found them with your link. Thank you

Thank you for the repair reference swathdiver. I could not find OemCarAudio on ebay.

I got my first map update back in August and it did not install. I had to have them send another and that did not install. The HERE company knows nothing about the product all they are is a store-front for GM. I was referred to GM by HERE. So I called GM and after what seemed hopeful I found myself connected to a person at the HERE company. So it is just a big circle jerk if you have problems. Nobody at GM and Nobody at the Here company can help. I have now a truck with no gps, weather or map because the map update software corrupted the infotainment system. NEVER buy a map update from GM because they will NOT take any responsibility if things go wrong. I have had the truck at the dealer and spent 145.00 on labor trying to fix this but no luck. 2016 Silverado 2500HD

I bought a map update from Here company that claims to have the genuine GM/Chevrolet map updates. I will NEVER buy another update again form this company. The USB deleted my navigation system and never installed the correct map. The Technical assistance line is just a phone operator reading off a bunch of standard trouble shooting tips. I had to take my truck to the dealer and they could not get the map to install either. The HERE company is not helping and from what I can tell they can't help. They have no technical expertise. I spent 145.00 at the dealer plus the cost of the usb. At that price I could almost buy a completely new infotainment system module.
