OK, I don't quite follow -
If I rotate the dial (one click) this is button 15, if i continue (same direction) then the next click is button 14 (for example) - so that being said, the HUD brightness would therefore be ON (14) and then rotate again (15) it would be off. continue rotating would repeat the above ON/OFF, ON/OFF. How can you turn this into a "dimmer" switch - to enable one direction as dim to off, the other as dim to brighter..
Thanks
