This may be a dumb question, but did you have the technology package, or trailer camera package before you started this? Just talking with WAMS, (Chris) made it sound like if you didn't have one of those two, that it would be very difficult to complete this up-fit. I have an LTZ, and amazingly I didn't notice that I don't have either unfortunately. I don't trailer a bunch, but I would certainly like the 360 camera view. Thanks.
