AL Priority Firmware Update History (Running History)

[BestRadarDetectors]

I updated my firmware to the latest, and now the warm up self test never passes. Any idea why this would happen? It behaves like I am near a wall when I start it up. It just goes red and beeps continuously.

Probably because the new self check is more detailed to catch issues and not let you drive off thinking you are protected if it finds an issue. If its beeping a continuous 2 beeps and does not stop its either because all your sensors on one side of the vehicle are blocked or you have a sensor failure. You need to disconnect one sensor at a time until the alert stops and you will be able to troubleshoot which sensor is tripping the error.
