Nav radio in a 2003 H2

Hi i`m new to the forum traded a Cadillac Ecalade for the H2, I have used the search funtion but haven`t really found answer. Will a 2007 Nav head unit work in my 2003 H2 with the Y91 system I currently have? Thanks

I installed a nav from an 06 H2 into my 03 H2. You also need to add the antenna and a VSS wire to the raido from the speedo harness.

Yes it was a direct plug in with the exception of needing to add the VSS signal from the speedo. I wish I could say that the 2007 unit would fit but all I know is the 2006 worked perfect in my 03.
