Newer camera definitely uses different software (other threads confirm this), but it's easy to reprogram.
As for the grille/bumper mod, it's fairly easy as well, just a little time consuming. The new (2017) bumper bolted directly on to the 2009 body. The grille is different obviously, but it also fits the bumper and body without any additional requirements.
Only issues/recommendations: 1. New bumper must be professionally prepped, primed, and painted. 2. Fender clips and plastic engine clips are pretty fragile, and break easily. 3. You may want to get a partner to help with the install, since it can be hard holding the bumper in place while bolting on. And 4. Parking sensors were a bitch to deal with until I realized they just pry through the holes in the bumper, and do not need to be disassembled.
Lastly, I used a diagram someone posted in a thread here as a guide to where all the bolts, clips, connectors, etc. are (sorry I don't remember who posted it). It was the best help to me in this process. If I can find it, I'll repost the link for you.
Good luck!
