I am not that familiar with the 2005 malibu's, but I do know with the G6's, you are able to add functioning steering wheel control if the car doesn't have them, and they are able to swap from the 4 spoke steering wheel (similar to malibu?) up to the 3 spoke.
To add Radio controls it did require a trip to the dealer to have them program the option into the radio (I think it was RPO UB3) but it was doable.
Here are some links:
