Honestly, it is a programming issue.... All the buttons on that side of the steering wheel send thier signal down the same wire, I rewired and programed mine to work with an aftermarket Alpine deck. I have a few times where I will vol/track up/dn or mute and it will send two signals instead of once.... (meaning if I hit the mute, it will mute and un-mute). so if it is something that constantly happends, you could probably get it fixed. otherwise, probably no correction for it
