Stoo, there wont be a head unit. The amplifier will be mounted as high up in the console as possible and the inputs will be run to the cubby under the seat. The sat radio will plug in there and will be interchangeable with an ipod. The previous owner of the boat had a head unit mounted directly below the steering wheel but I have put our switch panel there.
Linda, I would have to agree with Stoo on the build quality of Hurricanes. Since this is my first true rib I don't have too much to compare it too but everything on it seems over engineered. I will also be looking to upgrade to a 5-6 m hurricane or Avon next year. Good luck
