Z120 problems with parking assist button

[vietcu]

Hey guys, I have this problem with my truck and it is kind of bugging me to the point that I need to ask for a solution. I have had this unit installed for a few months now and everything is working fine, with one minor problem. I have the 3 buttons to the very bottom that has to do with parking assist (middle button). Because it is so low in the console sometimes it is touched by accident with stuff I put in that little box, when it is touched and the lights come on. The 120 shuts off. I have to then press the parking assist button again, and wait until the light goes off on the button for the 120 to come back on. As long as I don't touch the button everything works fine, but sometimes I touch it by accident and off it goes. Not that much of a deal, but kind of bugging me now. Wondering if I wired something wrong?
