Can anyone clear up a question I have about the combox upgrade? I have a 2014 Z4. I am told that in order to use the iPhone app to remotely lock/unlock doors, start the car, adjust temp., etc I need a combox upgrade from the 2g box I have to a 4g box. My question is if this will work and if I can use the app only after the upgrade or do I need to pay for the monthly subscription to Assist Drive/ConnectDrive or whatever it is called?
Thanks for you help,
Barry
