I had the telephone module on my previous 911. I don't want to use a SIM card with a car anymore. Ever. And that is the main difference between the two options as far as I know. The external GSM antenna (which I don't know if it has 3G capabilities) works only if you use a SIM card. If you still connect through Bluetooth is the same thing as my option.
Not quite. With the telephone module the phone is connected via bluetooth to the car's main aerial for much better reception and less battery drain on the phone.
isn't that only if you have SAP (SIM Access Profile) Bluetooth phone? SAP is not on my Sony Ericsson Xperia Ray, for example.
