: Unlocking a navigation unit

05-13-07, 10:40 AM
So I am buying a stock navigation gps unit off a guy to put in my 2003 and he said that it was locked to his Escalade for security reasons. He told me that a dealership can unlock it for me but does anyone know how to do this so I can just install it myself? Thanks.

I'm pretty sure you're going to need a Tech-2 to replace the VIN on the nav unit with the one from your truck.
