I have a 2020 Chevrolet Silverado 2500 Highcountry. They have added a "timeout" to the system that turns ACC to OFF after about 10 minutes disabling the WiFi. I have tried a few things to possibly circumvent the timeout function including exiting from passenger door, leaving the wireless key fob in the vehicle, leaving it unlocked, etc. No luck. I really wish I could find a harness that I can add in that keeps constant power to the wifi module. Wifi module has to be pretty low power and I have duel batteries in the truck. Also, would be nice to hack into the infotainment software itself as it is an open source Android platform... Anyways, if anyone comes up with anything PLEASE POST! I will do the same.
