Despite it stating that the 512GW rear camera will display fully on the screen for use as a reversing camera, I've been uable to get this to work, and wonder if anyone else has had any success? I've contacted Nextbase support and they resonded very quickly to advise that I need to update the firmware to 22.5 for this feature to work in the Mode setting. Followed their instructions but unfortunately despite checking and confirming that it's now on V22.5, there is no extra camera selection in the Mode settings. I've emailed Support back but in the meantime wondered if anyone with a rear camera, has managed to overcome this?
