I have had a couple false POP alerts on my X50, and have lately turned POP off, as it's not used around here, anyway. I will post the software version in the sticky message... but this is is even stranger:
Under hard acceleration in both the car and on the bike I can get the laser alert to go off. Now we're talking HARD acceleration, like wheely popping zero to triple digits, not general driving conditions... and it's only pulling away from a dead stop. Easy on the bike... do-able in the truck with some effort (though obviously not attaning the same rate of acceleration, or speed). The alert continues until I back off the gas.
I can also get a laser alert when I honk the horn in my truck! Now that's not right!!!
Both locations the X50 is powered from the battery of the vehicle it's riding with. Settings are as follows:
POP off (now)
City low X
Auto mute off
brightness - last
Tone - loud
After a few months of use it's saved me twice... so these quirks aside, I'm a happy owner.
