I recently purchased a used 2013 CR-V with Nav because it was equipped for towing four wheels down. It wasn't 30 days until somebody caught my lower rear bumper. I decided to change the lower black plastic myself and ordered one on ebay for $126. I tackled this one day and found the job to be quite challenging. I advise anyone that tries this to make sure they understand the proper placement of the rear plastic pieces including the underneath large piece and the splash cards. I didn't pay enough attention and was puzzled for a while trying to get it back together. The two clips under the taillights took the most time but I finally got them off. Six hours but I was determined and I got it done.
