navigation update

[gmcjay]

question to anyone who has tried or knows, i have a 2007 (new style) sierra with navigation, it needs to be updated by a cd from what ive learned( doesnt work right anymore). my question is can you use this cd on more then one vehicle or is it a one and done kind of thing?

It has to stay in the radio to work.

its a dual layer DVD , it has to stay in the slot behind the screen for the mapping to work

hmmm....it worked up until a few months ago and the orginal cd/dvd has been in the glove box since i bought the truck....interesting

Unless you have a 2012 or newer navigation unit the DVD has to be installed behind the screen in the nav disk slot or the unit will absolutely not work.

ok i guess ill have to investigate this haha.... how do you open the screen?

[louie730]

Press the Menu button until you get the Configure menu- (Sound-Radio-Nav-Display Time)- at top of screen.

Touch the Nav display button on the screen.

Then press " Map Database Information" button on the screen.

This will bring you to the Navigation Map Database page.

Touch the " Change" button at the bottom left of the screen and the screen will fold down so you can remove the map DVD.

When you are ready to install a new DVD or replace the old one, insert DVD and touch the "Close" button on the screen.

This should do it for you. This slot behind the screen is only for the map DVD- do not insert a CD or other DVD in this slot.
