as i don't have a m3 , but for those who do, i have some questions about the connection: 1) is the bluetooth feature is necessary at all times to lock, unlock, send any commands to the vehicle? 2) if someone else is in the car and i'm the driver with the connected phone, and i step out to pick up take out food, can I leave the car ac running with my phone on me? do i need to hit any special command to leave it running or is it a , i step out and it continues to do what it does? or do i have to leave the phone inside car with the passenger? 3) since it's bluetooth and let's say I do step out of the vehicle with the passenger inside, and i'm 20 feet inside a store(i assume it's still connected), will any phone calls ring to my phone? to the car? can I prevent it from going to the car all the time? seems frustrating to be bouncing back/forth. 4) also, can the passenger(s) view all the text/phone call logs on the center console while my phone is bluetooth? can that be disable? 5) is it any different in the S vs the M3 as far as customizations? since I saw that there are more in the MS thanks in advance.
