Nav Dvd Updates For Upgraded Delphi Touchscreen

[rupertjl]

Hello,

 

I have an 04 Yukon Denali XL that I upgraded to the Delphi Touchscreen nav/radio unit. It came with the version 3.0 nav disk. I would like to upgrade but how do I find out which part numbers of nav disk are useable? I can go to the GM site but it assumes I still have the OEM nav radio in it...are the part numbers still applicable? I also don't want to but the newest version but keep my eye out on Ebay for something in between. Any sites out there that can help me?

 

v/r,

Jud
