2008 and Nav Radio
I know this is going to come up. 2008 H3's came out with a new ONSTAR module this year. If you decide to change out your current radio and put in a factory Nav Radio, it will probably not work. The new ONSTAR module will stop the Nav from working. In factory 2008 H3's that come from the factory with Nav Radio, we are putting in a different ONSTAR module so it will work. If you decide to do this, you will need the other ONSTAR module or one from 2007 model which is close to the same.
