I do not think the MGM radio would work because of this

and this

Due to the part numbers stating that its only a 05 CV/MGM radio only. Does not work for anything backward or forward.
As far as stock radios, you have to be careful because the radios need to go like this. Where the front is like 1.5 DIN and the back is 1.0 DIN due to the ductwork.
