I'm in much the same position .. don't want to sell my Rio, but can't install it in my new vehicle - I have the original box, documentation, CD, a NuFace Bruface installed, (still have the original face plate and buttons also) three different colour original lenses, two original remotes, two AC adapters, a pelican case that has been carved out for it, Mlord dock (new - never used, unpainted) - the Rio has had the illuminated button hack done to it, works great - I also have the lens pallete to change the colour of the buttons to whatever you want - full range of all colours. You can see my Rio, case, etc at my web site. I think that $800 US is not unreasonable for this complete kit. If anyone is sincerely interested, let me know and I can always take more pictures, or with the wonders of modern technology, 'show' you everything over msn video meeting..
