2003 Denali Touchscreen Navigation Upgrade

tjferris · December 16, 2008

Hi all,

I have a 2003 denali, it has the Y91 lux bose system in it. I have the factory NON navigation radio currently. I Just purchased a 2005 touchscreen radio from a wrecked Escalade, P/N 10377531. I need to know what the P/N of the gps antenna that will work with this radio is. I was on gmpartsdirect.com and there seem to be quite a few different numbers from the one they offer to other forums I have seen online. The prices range from 20 bucks to 70 bucks depending on what part number I search for. Can any one tell me for sure what antenna I need to use with this radio and my 03 Denali. Thanks!! Also what are the major dif between this radio head unit and the 15800001 P/N unit? I know the 15800001 is the newest revision but is there anything earthshattering different between the two?? Can the dealer upgrade the firmware on this radio to match the 15800001 unit or were there some hardware upgrades on that unit as well? I don't even know if you can update the firmware on these radios thats why i'm asking!! Also what lockpick device do I need so ALL the navigation functions are available while the vehicle is in motion?? (so my passengers can input new destinations and search for POI's ) Thanks for any help you can give me!!
