Gps + alp

[BestRadarDetectors]

just a guess but, both the plus ant and the lider wont operate because they are below the threshold set

I have not tested it yet but it should be the opposite. Protection takes priority over any feature and AL has always gone this way. If the GPS can not determine your speed it would not filter the alert. The same would be if you were under the set speed when you got hit and you just crossed over your speed setting, even though it was originally ignored it will alert and defend the moment you cross past the speed setting.
