Nav Unit

[gw62112008]

I know that this may have been covered before but here goes for my specific application.

 

I have a 2007 sierra, new body style with the stock radio single cd.

 

What i want to do is install the in dash nav unit, what would i need to do.

 

I work at an independant repair facility that does have a tech 2 with full programming capabilities and i know this also has to be done, no big deal. But what about wiring harness etc.

 

thanks,
