I decoded all the RPO codes to find out what options my EXT has and I found code:UQ7 Premium performance enhanced audio bose. Would this be what is referred to as the LUX system? In looking through the entire list of RPO codes I could not find anything with the description "LUX".
I am thinking of swapping in a later model with the touch control Nav. so I need to know what I have in there now.
With a little more research I figured it out. I have the Y91 code so I have the LUX.
