'05 Nav unit in '03 Denali

[zutoo]

I have an '03 Denali with factory navigation. I just found out the '05s come with touchscreen navigation. Does anyone know if the wiring is the same? In other words, would I be able to pull out my '03 nav unit and put in an '05 without doing any mods or having any problems? Thanks..

If you find out, please let us know! Supposedly, the '05 kit at jpcustoms.com will work on Tahoes/Suburbans/Yukons but for some reason won't work on the Denalis/Escalades, according to the disclaimer on their site (they don't mention exactly why this is)...
