I think it's most useful for a convertible where the small rear window gives you a big blind spot. It makes parallel parking in tight space much easier. I've found adding one after market can be difficult to do cleanly. I remember a lot of people pulled out the trunk lock cylinder and put it there but now they've eliminated that, and you can only pop the trunk with the fob.

 

I love it. It makes parking in tight places much easier.

 

My wife has one on her SUV on the navigation screen, originally I thought it was a gimmic but now I love it. It's easier to use than mirrors, and eliminates the over-the-shoulder-neck-twist-to-make-sure-nothing-is-back-there move when backing up. Wish i had one in my Mustang, but don't have the Nav system and don't like the spoiler setup. Maybe someday when I upgrade the radio... and I find a better place to mount the pinhole camera.

 

Hey, I have a hitch! It's the only way to get my track tires and tools back and forth without messing up the interior, since it is just too far to drive on slicks.

 

I just installed a Pyle PLCM32 with its univ mount camera which sits under the ledge over the license plate.

 

That's where I mounted my camera as well. a perfect place and you can barely see it (at least on a black car). I did a Ford rearview mirror with LCD screen retrofit, but will probably use the nav screen when I put in a head unit with NAV.
