First, if you are 300 lbs don't lean too hard on the armrest.
Second, when removing the back panel from drivers seat, don't connect any wire harnesses that aren't already connected. As apparently this will result in your radio shutting down and the alarm beeping for the mandatory 5 minutes.
I did fix the arm rest though but until I remove the battery cable in hopes of resetting the radio I had to pretend the beeping was some euro techno pop
on the cruise to work today. Peace out!!
