Switch on
If the ignition sense wire is connected, the car kit switches on when you
turn on the car engine.
If the ignition sense wire is not connected, press the power key. If no
device is connected to the car kit within 10 minutes, the car kit
automatically switches off.
After the car kit switches on, it tries to make a Bluetooth connection to
one or two last connected devices, depending on the Multipoint
connection setting.
