Instructions for installing an OEM Nav in your '07 w/JBL
You need to search in the GPS/NAV section. There are many post about this. Check out the link, page two has a PDF on how to install on your non-jbl truck and page three has the name of the person in Canada that you will have to call to get the right wiring harness. As far as I know you can only get that wire harness from Canada. Good luck with your install.
