Backup camera (factory install)

Good luck - there is none...

This is why the Toyota system costs $soooo much - it comes with wires - which must be routed up front...

Mounting and installing is fairly easy and straight forward - it's documented all over the place here... Cameras that fit the same opening are readily available on EBay delivered for $30 - they give a VERY good color detailed image (you can tell which side a penny is laying on the ground) - and add distance lines (which really help)...

Of course, you could get the dealer to add NAV+camera - i'd guess that's around $3.5K (after purchase add on)... As a bonus, you'd get the JBL amp, and a few new speakers...
