There are different flavors of the Limited. For example, some come with navigation systems, some do not. I think some have the tow prep option, and some do not. I think the backup camera may be optional as well.
Basically I think it depends on which factory options package is included.
My dealer is selling a V6 Limited with tow prep, backup camera and Premium Plus Value Package for roughly the $29,900 price you mentioned.
That does not include the navigation system.
Silver 2012 RAV4 Limited V6 4WD with Tow Prep and OEM Hitch.
Long live the RAV4 V6!
