Looks like it will work...but you just need to connect the VSS signal; which is not present in the factory harness on an '03 (since nav wasn't offered that year).

Get the metal bracket to mount the antenna... it is the antenna ground.
Call around and find a GM dealer who KNOW's what you are talking about... not all of them do. Give it 30 miles to start to track correctly, it will.
You will need the disk and antenna, mine came with both for less - but I think I found a deal.
