and id like to install it and to retain the factory steering wheel controls. i dont use xm or onstar so neither of those are a concern for me. so what im after is what harness i need to connect this to my truck and also what adapter i need to retain the steering wheel controls. i did some reading around and came across this

to me this looks like what i need, but its 180 bucks and i was hoping for a cheaper option. so if anyone can lead me in the right direction, and also perhaps a guide to removing the factory deck, from what i can tell i need to pop the trim panel off and then hopefully just unbolt it. ill eventually integrate a back up camera with this thing but for now id just like something with nav built in to it.

i also found this thing after searching around here for a bit
