Navigation Unit

[nolan11]

I have been looking for an OEM Nav or Aftermarket. I really do not know which one to get. I am going to attempt to install it myself so the OEM unit might be a little easier. I have and Early build 2006 H3 and was also wondering if the wiring is there for the Nav Unit and if a 2008 Nav unit would work.

Also is there a write up anywhere for steps on installing the OEM Nav unit?

I know that the aftermarket ones provide more for the price but really want an easy installation and don’t want to mess with different wires and connectors to make sure the Onstar and chimes work right.

Any help would be great,
Thanks
