Review on Enhance Your Ride: PAC BCI-CH21 Backup Camera/Navigation Unlock Interface for Chrysler/Dodge/Jeep/RAM Vehicles by Michael Keitt

I used the PAC BCI-CH21 interface unit to display the backup camera image on the factory radio screen. The only thing to note is that if you have a manual gearbox, you need to download the interface box with the initial version of the firmware (V1.1.2). I only use the rear camera function, so I can't say how well other functions work with this firmware V1.1.2. I used the camera sold here at Revain: https://www.amazon.com/gp. /product/B015Q78KSU/ref=oh_aui_detailpage_o03_s00?ie=UTF8&psc=1This camera fits my 2009 Challenger SRT8 perfectly with no modifications. It uses two screws that hold the rear license plate light. Just remove the license plate light and replace it with this camera (which also has built-in lights).
