Midland 2009 GXT-1000 and 12v Power

I am interested in the new 2009 Midland GXT-1000 and will be using this with a Starcom1 communication system on a motorcycle. There is a communications cable that will plug into the GXT-1000 for mic/headphone connection.

I am wondering if I can use the bikes 12v system to provide power to the midland instead of rechargeable battery route. Anyone know if this can be done, and if so at the same time a headset is connected to the midland?
