nav system availability

Hey all! Had to head to the dealer for service today and decided to check on when my dealer was expecting his 04GPs. He has his first on order, due 3/17/03!!! We were able to check out options on their order system. Two different GTs (GT1 GT2) and a GTP. The GTPs all have 17 inch wheels. Sweet. One of the radios is XM-capable. What I did not find is a Navigation system. In talking to Delphi (formerly AC-Delco), they state that the 04GP will have a GPS system available. So the question is, when? Has anyone heard when this will be added as an option?

Thanks,
Frank

I've heard from reputable sources that the Nav system will be available late '04 or early '05.
