All in a sudden my memory buttons seem to have stopped working. The 'Set' switch doesn't light up. However the steering wheel moves when I press any of the presets. I couldn't locate a fuse for this in the user manual. I did recently wire a radar sector to the fuse box. Just trying to see if I may have accidentally knocked something out, before I take it to the dealer.

 

I have been told that there are only a few places you can run wires to hard wire a unit into, you may want to contact one of the radar companies such as escort and they will tell which place in the fuse box to hard wire, until then, you may want to try disconnecting the radar detector and see if everything starts working again.
