Right now we have 11 configurations so I'm not sure if it's even possible to reduce the options without causing even more issues. If the Navigation option is split from the Solar package and the Advance Tech package, you've dramatically increased the configurations. And if you further split the Navigation into choices of Navigation screen + Backup Camera only and Navigation screen + Navigation + Backup camera... If, production wise, Toyota can't increase the configuration options, I vote to keep them as is and not eliminate a further option we currently have. Or at least don't do anything until I've already got my Prius!
