Hyundai Genesis 2015 backup camera
The replacement of the camera itself is part number: 95766-B1100 which works in Genesis 2015-17 per my ebay searches. Us pricing is about $130-$150. But you can buy from overseas for $90-$100 with a month or longer delivery.
Similar partnumber is the full unit with camera and trunk latch release. As shown on amazon

There are tech bulletins on possibly wiring harness issues to cause camera issues
Interesting info from a forum on how to replace and recommendation to not just buy the camera but the whole unit as it is easier to replace.
