300c 2014 Backup Camera problem

There are a bunch of videos on Youtube if you search "2012 Chrysler 300 camera replacement"

This is a common issue, especially if there is a sub in the trunk. If you pull down the covering on the trunk lid, check the wiring going into the camera, brake light. That seems to be an issue with the trunk slamming closed. If that doesn't help, you can purchase the camera separately.
