I saw a video put out that showed the backup camera having enbeded left and right fender camera views along with the main rear camera view. I see these cameras on the DASHCAM playback but I did not know that these can be inserted into the main backup camera view. How does one set this up as I think this is great especialy for me, being from the older set, who needs detailed instructions on how to work with things such as this. Thanks to all.
