    Laser Diffuser:K40 Vs. Lidatek?

    Anyone have any experience with either one. I really need to get one of these for the GT3.

    Re: Laser Diffuser:K40 Vs. Lidatek?

    I have a K40 remote system in my 996 Cab and it works very well, including the Laser Defuser buried in my front grille.

    No knowledge of the other system.

    Re: Laser Diffuser:K40 Vs. Lidatek?

    Here is a review of each from the UK speed trap experts

    K40 diffuser
    Lidatek (a.k.a. Target in europe)

    K40 on an X5

    The laser diffuser is just above the license and the radar detector antenna is to the right. There is another detector antenna behind the rear bumper.

    I wish it were a little less obvious. If the patrolman sees this there will be no hope of a simple warning. It is better than the license frame laser jammer K40 offers which is really obvious.

    Re: K40 on an X5

    Here is the interior installation I have. The knob to the left is the volume and the ring surrounding it is city/highway/off. The left and right red lights are radar warning lights for front and rear. The yellow light is a power/filter indicator for city. The unfiltered indicator glows green.

    The controls and indicators are very customizable and could be placed anywhere. I cannot comment much on performance yet, I have only had it three days, except to say I am not getting the large number of false alarms that others have complained of on this unit.

    Lon: Lidatek from what I hear makes a great system.. check out this article from Audiworld:

    No, I paid the BMW dealer a bunch of money to do it. It is a nice install. If I did it I would have taken 4 times as long and not done as well. Plus, I am getting an air suspension error message now. Probably unrelated but if I had been rooting around in the electronics to install this BMW might say it was related.

    Re: Laser Diffuser:K40 Vs. Lidatek?

    Hey Lon,
    From what I've heard from one of the best audio/video install shops on the West Coast, K-40 is outdated, and they stopped selling/installing it. They now use the Passport SRX, made by Escort. You can learn more about it at I'll probably go with that when I get my C4S.
