: Navigation Question

06-09-08, 04:23 PM
I did a search and couldn't find my exact application. Hoping some of you guys could help....

I just purchased a 10377531 Touch Screen Nav off of ebay for my 2003 Escalade. From my own research I believe I need this antenna: 15135178 and want to confirm and also need to know which is the most current map disc for this unit.

This should be plug and play then correct? I have the lux option for my escalade.

Thank you for all your help!

Yes you will need the GPS antenna, it mounts under the dash pad in the dash frame...yes, basic plug & play, if theftlock activated a trip to the dealer to setup...check with the GM navigation web site for the lastest map, last release was late 07
