I have a Cadillac xt4 when I try to use Pandora it just says waiting for coverage and it will never load. The dealership ran a full diagnostic on my wi-fi system and they say it works perfectly. But when I use it through my cell phone some sites do not load. Then it will say no internet connection. When I use Pandora through the my apps section of my cell phone it does the same thing will not load.
