Toyota didn't come out with the backup camera for the Prius until the 06 model. Therefore, no cable is there. In addition, the the MFD was changed in 06 to a higher resolution.
Thanks to everybody. That's not good... Strange, the seat for the camera in the hatch bottom does exist, there are only 4 holes to drill. Maybe this is unified with Japanese model which has auto-parking...
Check out Sigma Automotive Sigma Automotive – Toyota Hybrid Prius 2004 - 2009 OEM & JDM auto accessories they have a back-up camera and an interface unit for 04-05 (if you have nav). In parts you will be out around $500. A cheaper alternative would be to purchase a navigation unit with a wireless back-up camera.

Thank you. I hope to do this cheaper. Camera lockpick (WOULD ANYONE HELP ME WITH BUYING IT?!) for $175 + $65 to Russia, and OEM 2006 Prius camera (already bought for $200). At last the cam is installed into its native place.
