Once you get used to them, they are tolerable. I've had enough pioneers in my day to memorize all that crap, dad has one in his old car and calls me EVERY time he wants to activate the aux input cause he unhooks the battery for storage. I actually like the amount of equalization they have but the built in amps suck compared to other models. The real reason I have 2 of them is because they look less cheesy in the dash than a standard din unit, one was free out of a trade in and one was cheap outta the JY.
I guess, I can walk 10 steps to my car, pull 1 bezel and 4 screws, and snap a pic of my harness for you. Hold on...
