Switch on
If the ignition sense wire is connected, turn on the car ignition. When
the car kit is switched on, the indicator light of the input device turns
on.
If the ignition sense wire is not connected, press and hold the Navi
wheel for about 2 seconds. Alternatively, turn on the ignition, start
driving, and wait until the built-in motion sensor switches the car kit on
automatically.
After the car kit is switched on, it tries to make a Bluetooth connection
to the mobile phone that was last used with it.
