After learning quite a bit from this site, I bought a dual LI for front, along with a 9500ci.
I did the install myself with help of a few friends. Along with the 9500ci and the LI, I also installed a backup camera, a navigation bypass switch, and an audio/video harness. The whole thing included two sensors on the back, three on the front, as well as three panels, three switches, three cpu boxes, the radar GPS, one speaker and one LED all installed inside.
Here are the photos of the final result:
It was about 20 hours of work to get everything installed. None of us had any experience on car installs before, but we took our time, had lots of fun, and I am pretty happy with the result.
