[Help] Car Radio Audio Options
My new Colorado's radio has the usual choices for audio settings, bass, treble, fade, l/r and one for "M 10". Never heard of that one and both the salesperson and myself could not figure it out. Since the truck has built in bluetooth and OnStar I was thinking it might have something to do with the mic levels.
Nothing in the manual and could not locate anything on the net. Any ideas ? This is the first new vehicle I bought in 10 years.
