From what I understand there are two bose systems. The one that is the most common is in the trucks ,suburban / yukons. The other one that has the lux amp is normally in the cadillac's and denali's with the touch screen nav systems.
I am not sure if the lux amp is used when the dvd nav system is not installed. I currently have the bose system in my truck. I am looking for the lux amp. I will be doing the dvd nav system in the future. Can you take a few pics of what you have?
