I have one. On sunday i took it out to plug the Steering wheel controls lead back in. Tonight, i went to use my remote control for it, and it didn't work. Tried different batteries, still didn't work. I've had the H.U. out plenty times as it's been in 3 cars, and i've never had the remote not work before. Been through my settings on the H.U. and can't find anything different from usual either. Last time i remember using the remote, was about 2 weeks ago, and didn't have any problems then. Thought there may be some way that i could of un-programmed it? Any ideas anyone?
