Bought the Wrong Navigation unit.

I found a 03 Yukon Nav unit locally and bought it for a project I'm working on, but I didn't read up on GM audio systems first. I guess I can't throw this thing on a motorcycle :(

Does anyone know if the non-Lux version can be used without having all the GM bits?
Can I just get a LUX amp or will I need anything else?

Thanks for your help.

If there is no way to make it work, Is anyone looking for the LUX version p/n 15204335.
