yeah there are 3 options for "key color" in the settings. I have the s100 unit in my Colorado and that is pretty much the same setup but wince6 and on that option 1 is green option 2 is red and option 3 is green. on this s160 unit the 1 and 3 are green but option 2 does not light up, so its a software issue or the led driver for the red leds is stuffed. my ac controls are not working with this unit atm. I think the canbus module I got is faulty, waiting for matt to reply and maybe send another one. if that don't work its going back lol, cant have a non working aircon. it will be a shame if I have to send it back because its pretty decent, droid 4.4 with 5 in the works and the nav is all android based not wince.
