I tried it at 20 sec, 25 & 30 and even that seemed excessively long of a delay. I quickly reprogrammed it to 3,5,7 and it's worked 100%. Probably 3,4,5 would work too but it's not worrying playing with. Removing the dash again to rewire the green to always on is probably worth it, when the unit starts with no audio playing it doesn't trigger. Tried to load the Apps screen without starting music (ie applying voltage to the green wire) and the appradio didn't recognize the parking break as on. Had to back out and start the radio manually to get it to work. Might as well have a switch in that
