So I picked up my 22 Yukon XL in July. I hooked my Samsung to it with andriod auto and everything was fine when I used the navigation. I rarely use it but it's a nice feature when it is needed. It stopped working and I called OnStar and apparently you have to pay for the wifi data package to use the nav feature. My phone has nav for free but somehow it won't communicate the map info to the truck screen and I have to disengage andriod auto and use bluetooth only so Google maps can give the directions to my destination. Does anyone know of a way to have the map and nav info from my phone get sent to the truck screen? Any help is appreciated!!
