I think you are beyond help ?
Basically Assist is the package whereby you can i) Press the SOS button in your car and be connected to emergency assistance, ii) Get concierge type help i.e. "Where's my nearest petrol station" and iii) Now get addresses sent to your car nav via google maps.
The other service (Online?) is for texting/emailing/surfing from the car.
That what you are asking?
