Anyway to upgrade a non nav 05 STS to a stock nav system?

That's a really good question, I eagerly await a good response...

I think it can be done through GM, but I don't know for sure...

WildwoodBill,

I am about to buy a Nav/DVD system off ebay from an 05 STS and replace my stock 6 disk. Was it as simple as unplugging one and plugging in the other or did you have wiring modifications?
