So did some digging:IM HOPING you can do that. Some systems won’t let you do it that way. Share data and info from the source. But we shall see.
Because I agree. I would not use the fords data plan if I had to.
FordPass Connect (optional on select vehicles) and complimentary Connected Service are required for remote features (see FordPass Terms for details). Connected service and features depend on compatible AT&T network availability. Evolving technology/cellular networks/vehicle capability may limit functionality and prevent operation of connected features. Connected service excludes Wi-Fi hotspot.
So it looks like you can't share your data from your phone, but I don't see any reason why you couldn't use your phone's data for streaming things to Sync-Like Waze etc.
