Disconnect or shield the antenna from the cellular modem, and wifi equipment in the truck. Of course, that will also cause all kinds of other issues. Nearly all modern vehicles (built in the last 20 years) can/do report to someone other than you.
Agree. Drove a Marsh Gray yesterday and they had a f150 or SD in Avalanche sitting on the lot. I was going to wait for a 26, but after seeing Avalanche in person I decided to buy a 25. Def do not like that color.
