Yukon owners suggestion for nav system?

Yukon owners, would you recommend the factory nav with back up camera or purchase an after market nav system? Which would save me more money, including installation. I currently have an 08 SLT with Bose system.

OE system I would say, Mine didn't come with NAV and I'm looking to go with OE as you retain the steering controls plus with Bose and running non OE you will run into little things like loss of door chimes & turn signal sounds so I've heard. for $700-900 you can pick up a used/new take out NAV system and it will retain the factory look.
