I have a Dyna box with 1 ride on it that I will sell you for $180.00 that has 1 ride on it with ALL the original paperwork & box. It works great & is off my 05 so will work on your 06. 03 & 04 model has a different plug & won't work. I got an LTR & gave my LTZ to my 16 year old so he DOESN'T need it. It works absolutely perfectly & I will guarantee it! Ray.
