I have nothing but high praise for Sheehy Toyota of Fredericksburg. Both the service manager (Bill) and one of the service writers (Tarron) have Supras and are very careful with the car (being owners themselves).
I would not bother going to Passport Toyota since they don't really care to work...
I get the same thing but I am able to stream music and get Waze to work just fine over cellular data.
It comes down to the wireless connection to the car itself doesn't offer internet access (which is normal).
