Help!! Installing oem like new nav upgrade

[WickedZ71]

Hi all,

 

I have an 09 Silverado LT z71 extra can short bed that is a non Bose. I found a like new navigation head unit and need to find out if I can do the upgraded oem nav on a LT. I've read that a dealer may have to program the vin into the head unit. Any help would be greatly appreciated as I'd hate to have hundreds invested in a paper weight.

 

Thank you
