: 2010 Escalade Navigation Install/Programming Problem

10-20-12, 01:33 PM
On a 2010 Escalade, we tried to install a used USB navigation unit from another 2010 escalade and when we took it to a local GM dealership for programming, they told me that any used radio will not reprogram in a 2010 and up Escalade model. They tried it any way and it would not boot.

That does not make any sense as any other escalade, tahoe, or any GM navigation unit for that matter programs to another vehicle using the Tech II programmer.

Any solutions?

We purchased a used GM escalade navigation system from California and installed it. Everything works fine, but the GPS unit still thinks we are in California.

How do you tell the GPS unit that we are not in California anymore, shouldn't it acclimate?

Please help, thanks!

Did you install a new GPS antenna with the radio?

No, not a new GPS antenna.

Did you upgrade from a non nav to a nav unit? I should have asked that before.

Does the screen have the GPS word with the slash?
If it does then it is not getting a signal. When all connected properly, it should automatically pick up your current location.

The NAV unit also needs to be programmed to your VIN.

Yes, it was upgraded from a non nav, now it has nav. Yes, the GPS word has a slash, so it is not getting signal. So just check all the connections?

Anybody ever changed or upgraded to a GM OEM nav unit in a 2010+ Escalade?

Did you get a GPS antenna with the radio? It goes under the front dash panel and it has a square blue plug.

No antenna with the radio. Arent the escalades pre-wired for nav, and come with a GPS antenna even if the car came with a regular radio deck?

No it does not come with the antenna. It is a separate piece. I could get the part # when I go into work tomorrow. I've done several of these upgrades, but could never remember the antenna p/n.

Ok thanks for all of your help cadman. I can get the part number, now worries. Thanks again!
