have a fflip out clarion, yeah, when flipped up it blocks off the controls to the aircon - but I have mine mounted in the top DIN slot, it wouldn't if it were in the bottom (don't think so anyway), you can still reach the aircon power/temp knobs, and the off button isn't obscured at all. DOes this matter? not really, its climate control, set the comfy temp and then I leave it, and the screen has a dip function so it'll drop down for a few seconds and then go back up.
