Ok I have had an m4 for about a year and I have it. Set up fairly standered. It was working well up until a few days ago. Now when it has any 12v+ it turns on(not waiting for the igntion on, then waiting 5 sec. To turn on and then giving an "on butten" to turn on the mobo) I didn't change anything it just started doing it one day when the battry got low and I tried to start the car.
So now if I turn off the ignition the m4 will stay on untell I disconnect the battery.
I did a search and couldn't find any one else that was had this problem so... don't really where to start with it.
Any idea guys?
