After much research, i found out the canbus socket under the beak will put out a maximum of 5 amps (at 12 volts, obviously). So when i fitted a sat nav on my bike i also powered my starcom system from the same point. This draws aprox 3.5 amps with the volume turned way,way up and the garmin working. With the obvious benefit of power being dropped when turned off. RESULT.
