2003 Denali Touchscreen Nav Radio Upgrade

[tjferris]

Hi all,

I have a 2003 denali, it has the 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?? Thanks for any help you can give me!!

also, is it possible for the dealer to upgrade or update the firmware in the radio when they unlock it? if its just a software or firmware dif. between the two model numbers? If it is a hardware upgrade that is a differnt story! Just a thought. Thanks again for any input.

Another question I have, Is there a lockpick solution available for this radio that allows input of destinations while the vehicle is in motion? I usually travel with other passengers and it would be nice to be able to have them search for POI's or add additional destinations while on the move. The only lockpick I saw for the 05 touchscreen units was for video.

Thanks
