looks nice, but I really not a fan of drilling , and I found this product: Guardian Alert, back up system, using microwave technology( act like a radar detector. No drilling and install in 15 min.
made by Sensetech.
I installed the autosonar ones this past week. Took about 5 hours start to finish, drill, install, hide all the wires. Def beats the 750 the dealer wants and work perfect, I love that in addition to the beep, I can see the distance on the corner of my dash. My CT is white. the ones painted white from autosonar are not an exact match, but close enough for me. I may buy some a small cynlinder of touchup paint and go over them once but I can hardly telll now. Slight issue I had, there is a metal beam behind the bumper, you can drill through that or install the two middle sensors a little higher on the bumper. I did that to avoid cutting into the beam.
