Pretty much same here. Not sure exactly but it's supposed to work but seems logical to me. The car is locked, the alarm is set, even in my garage. So it doesn't know who's pressing that button. Now, that said when I'm standing there with my phone you would think it know it's safe to unlock the port with a press on the cable just like opening the door. But no. I either just give the door handle enough of a tap to unlock but not open or press the port open on the amp on my way to the car; or on the car screen if I just parked.
