I would suspect it stops until the next month! Though the OTA updates will probably still work as they are also on the non-connect cars.And what happens when you've used up the data, does it stop working until the following month or do you have to register a credit card so they canfleececharge you ?
I'd imagine live updates doesn't take up that much data but I can see music burning through 1GB of data in a single month very easily even under reasonable heavy usage.Is that right the connect only has 1gb of data for you to listen to all your music for the month and your live up dates?
