H2 GPS Navigation Models?

[Hunt56]

I need to find out which GM Navigation Units will work in my 2003 H2. Can anyone list the model numbers here that can be installed in this vehicle?
Thanks to all who can help

You have lots of options. Your '03 has a double DIN opening (where your NAV system goes). There are many aftermarket units that fit this size slot. Be sure and check out the Panasonic Z1. It is very sweet. Doa search for NAV units here. You'll learn alot about various units that have been installed.
Good luck.
