    So I've had random F2 errors which at first I kept attributing to initial volvo Lidar interference (i.e when car starts and self tests are done) but it loois like the head is really having a connectivity issue. So yesterday I was driving from Florida to NC and I've passed 2 FL leo with their lidars shooting through the driver side rolled down window and no peep from alp. Then I passed two Georgia Leos doing the same thing and still no peep from alp even though my alp app was showing a blue car.
    I did have an F2 sensor check failed during a start up of the car though.

    So I pull over to get gas and I walk in front of my car and yeap one of my alps beeps as it should (upon my approach) but the other stays silent. So I pop my hood, undo the cable connection (the half turn screw on junction) and redo it. Now alp boots again (upon car restart) the F2 also alerts but now both heads beep upon approach.

    So my questions are:

    1) with only one head functioning does alp even detect ? Since it looks like it doesn't.

    2) the case of the connection being intermittent and requiring rejoining once a while, is that normal?

    Sorry typing on mobile

    Today I will drive from NC to DC border

    I recently had one of my heads fail with error 2 and in my case the error 2 went from intermittent to constant then the head stopped showing in my configuration. The good head still detected and jammed, but the system would give 20 fast beeps on startup saying configuration was different (as it no longer could see the failed head) ( finally had ALP relearn the single head only so it wouldn't do the 20 beeps on startup everytime) using the front selfie camera on my S4 I looked at the heads the good head received and fired when hit with my borrowed lidar gun, the failed head that wasn't even showing up in ALP config logs still received fine but didn't fire. so I had two receiving heads and one that fired back. That said it does depend on how your head is failing (presuming it is failing, occasionally E2 does happen) if you are only getting the E2 error occasionally then the head is probably working fine when the error isn't present. usually after I would get it I would power cycle the system and then it would be fine for a bit, but as the head failed it started happening more often until it was constantly beeping 2x nonstop. I have seen a couple traps using lidar and didn't get scatter either time, one last night where he got a car about 1/4 mile ahead of me and not a peep, you wont always get scatter, but sometimes you will.

    Wow. That's pretty rare. I almost always get hit in FL and GA.

    Well I saw a lot of them hunting without getting an KA alert ( so they used other means) and I saw few sticking their Lidar out (as stated above) but I can't honestly say that the Lidar was radiating (IE trigger pulled) since no alp alert.

    I guess I need to purchase an alp tester in order to see if my alp is detecting

    It is worth having a tester or lidar gun to check it periodically, ALP is sensitive but if the gun isn't hitting you or a car that's within ALPs view it may not catch it. It's only truely important that it catch it when it's hitting you ;)

    One head will detect any gun from any distance that a LEO would shoot you at; jamming is a different story. You might have a head going bad, yes. I'd dig deeper for an underlying issue.. What are the chances both heads are going bad and it's hopping from sensor to sensor?

    Even when a head is nearly toast, it will usually still detect.

    Tell her that when it is not alerting, the LEO repellent feature is in use...

    The payoff of having them isn't always immediate, it will happen at some point when you least expect it :)

    Laser traps don't tend to last very long as they usually get a victim pretty quickly and roll after them

    You probably weren't driving fast enough for the LEO to expend his index finger muscle.

    I have to agree, I have lucked out driving past traps that are just being setup. One was in a location where there are always waze posts, but no LEO's, so I always would roll up either too late (darn, just missed the trap) or at the right time (Yeah! just missed the trap). The ALPS pay off when the traps are there, but arent marked on waze and catch you by surprise!

    A late night wake up from a TruSpeed alert from an unseen (until on top of him) leo will make that ALP system priceless and fully justified!

    Even if they are looking through a gun does not mean they are firing. Most officers are trained and they don't pull the trigger until they see a speeding car. 1 Sensor would have no issue detecting and firing back.

    Good to know. I guess I am lucky in the sense of not being targeted ad caught (since I only have a dual alp on my xc60) but unlucky in terms of showing the value of the unit to my wife ( was secretly hoping on getting few hits so she would okay my TX expenditure :) :) :) )

    How does LEO target your car?
    Over here they always aim for the license plate cuz it is big and yellow.

    As a general rule I test my system routinely and especially before going on a long trip.
    Usually you would get a error code if a head has gone bad.

    I know exactely what you mean ...mine says ''its your money do what you want''
    then later she paraphrase ''all this money lost on gadgets,,,''
    That's why a save is so important !

    Exactly! I was hoping to ride the: "you see honey this would be at least a $260 ticket combined with lic points and increased insurance" ticket. But alas nope so no TX upgrade for me in the forsee able future


    What didn't help my case is that waze has caught 90% of them (ka and lidar) and 75% of just the Lidar while all my CM remained silent (leo running just lidar)

    Tell her you could be spending the money instead on going to a bar, and chasing after other women. That usually shuts them up.
