Car audio troubles HELP!!!?

I recently purchased a Freeway DVD-4383NBTi head unit for my 07, dodge ram1500 (Rumblebee) and the deck does not support steeringwheel control and there is no interface harness that i could find anyway that would allow it for this specific deck. Everythings hooked up and working except the sound all speaker wires are hooked up correctly i can't help but to think it's because of the steeringwheel controls is there anyway i can by pass the steeringwheel controls and just not use them for me to get sound? rather then routing all new wires throughout the truck.
