Has anyone had to replace their front 360 camera? I took a rock right to it and it looks like the part isn't that bad at ~$350 or so, but it seems like the whole bumper needs to be pulled to replace it. Dealer quoted $1450 all in to do the replacement and recalibration. I might try to do the replacement myself, but if I need to bring it in to get calibrated no matter what I might be SOL.
