If it were a power-cycling issue, it shouldn't be a problem when just the BT module is connected, right?

Does he have the ALP connected to a switched circuit in the car, so power is cut when the ignition is off?
You do need it connected to a switched power source, but shouldn't matter as the ALP goes through a startup process before connecting the BT. Instead of switching back to the control module, try going to the connect screen and pressing the power on your BT serial number.
