George:
Vince is going with your answer ... having no definite answer

Answer to all questions .... it is a series of three funny beepy noises and then it stops ... it only happens when you turn the engine off, it doesn't matter if you are sitting in the seat, standing .. makes do difference, it only beeps when you shut the engine off and no other time. If you turn the key on but do not start it, it does not make the noise. There is nothing lit up to indicate that anything is wrong or left on .... very puzzling.
We had the exact everything in this unit that we had in our 2012 accept for the beeping

. I looked in the manual and it has NOTHING about anything beeping or warning with a beep.
Guess we could call Kermit, but going straight to dealership might be the best as you recommended Ron, and hopefully we would not have to bring it in and they could possible be able to answer the question over the phone ... it would not be a part of the conversion so they should be able to help us ... I HOPE !
