I recently purchased a PL5300 Pop-n-lock for my 2005 Tacoma. I know, this PL5300 is designed with the back-up camera in mind, and 2005 Tacoma's don't have cameras....well, mine did.
Since I no longer have the Tacoma (new '08 Tundra owner) the PL5300 is up for sale.
It was never installed, so it's still brand new in the original box.
I purchased this unit for about $60 bucks shipped.
I'll sell it for $48 SHIPPED.
Here is a video on how to install the Pop-n-Lock on a 2007 Tacoma:
Here is an accurate image of what the PL5300 looks like on "Tactical Tacoma". He has the best picture I could find in a pinch.
