I've been running a week and many hundreds of city miles with lockouts and box mutes, etc. disabled. It's not perfect, but it is substantially better. I can drive by a grocery store without a single alert that I previously had many lockouts for.
It means you have the Custom Frequencies mute boxes enabled.
Go ahead and send the Max 360 back. I have both max360c and V1.2. Max360c is nice and quiet, but V1.2 is "mo betta" unless you want quiet and top tier range isn't necessary.I have an escort max 360 and V1gdn2coming, thought I would run them both for comparison, will they interfere with each other??
