backup camera without drilling holes...

I would contact Beat sonic directly and see what kind of deals they may have or if you can work any out.

I took a trip to San Francisco and it made parking in even the tightest spaces a breeze. I don't use it daily but its extremely handy when you need it.

 

okay, after doing a lot of googling and whatnot I found

420TVL CMOS Outdoor Back Up Car Rearview Camera 1 8mm Wide Angle Lens Waterproof | eBay

like beatsonic's screw camera but at a much cheaper price $29.99 (I'm gonna order it)

but looks like no one seems to sell a cheap interface harness by itself, so I'll probably have to get it from beatsonic for the $70 or so

 

Off the recommendation I ordered the camera from OttoNavi, but the power cord is way too short to run to the reverse light. Is there somewhere in the liftgate the power can be wired? I'm using an aftermarket stereo that will automatically switch to the camera input on reverse, so constant power to the camera should not affect operation on that end.

 

Check my guide here. Backup camera still works well and no holes drilled

Easily done with suction cups of the type used by GoPro and other cameras in track duty. I have both forward and rear vision cameras and once in a while side views as well. Consult one of the later car mags for a list of suppliers. and reviews.
