Another Nav Question

[Mr GT OH]

I just bought a 05 Yukon XL without a Nav unit, but I want one. What is involed with this and what Part # should I be looking for if the truck does not have the Y91 option code? Thanks in advance.

Looks like the latest model # you can use is 15800000.

 

Here's a link to those models on Ebay:
