    Unhappy Difference SR7 Vs SR7+ for use with ZR3

    I called Escort Customer Service today to inquire whether I could splice in a ZR3 lasershifter instead of the laser receiver to be told - that you can only add Z3 heads to the SR7+ (and not the regular SR7).

    To my my question how I could determine what I have - I was told to check the display. And in fact my display says SR7.

    Still, I didn't realize that there is a difference in the control units. And the Escort site does indicate that the ZR3 is compatible with the SR7.

    So did this customer service guy know what he was talking about ? If so I will have to return the ZR3 heads I just ordered.

    So is there such a thing as a SR7+ (I thought that the + indicated an SR7 with added Laser Shifters) ?

    Thanks

    This doesn't sound right. The ZR3 plugs right into the SR7 control box then you turn the shifter option "ON" in the setup. The SR7 (like the X50) was marketed as "Shifter ready" so I'm not sure what SR7+ means. But if you heard it from Escort CS then investigate it further. I upgraded my SR7 with a ZR3 ordered 3rd party, read the instructions. Bench tested it once then installed it on the C6 and it worked fine.

    Yes it was definitely Escort Customer Service. I called because I am thinking of cutting off the SR7 rear laser detector and splicing in the ZR3 rear laser shifter head allowing me to use the same wire (instead having to run another one to the control box).

    The response was - not a recommended approach but possible - as long as I have a SR7+ (because the regular SR7 can not be combined with the ZR3) etc.

    Sounded odd to me hence I asked several times to reconfirm. I still think it was BS - but I will call again to check once more.

    Yeah follow up on that.

    I would avoid splicing but having done an install on at least one German car I can only imagine how difficult it must be to re-route.

    Here's the differences, as I have the SR7+.

    The SR7 has shifter style laser heads but they are "receive" only, meaning they don't have the LED's in them for jamming.

    The SR7+ is the same unit, but the heads are shifter heads for jamming.

    The SRX is the same as the SR7+, except it also includes the option for voice alerts, and it is mainly sold through car dealers for install.



    Also i'm not sure if splicing would work anyway, as the wiring may be reversed, or since you have receive only units, they may not have all the wires that the shifter head has, as it does more.

    I don't have the Sr7 to test it out, but i suspect possibly if shifter heads are plugged in, the "shifting" option should appear in the options menu. but not sure.

    Ok, that makes sense. The SR7+ is a SR7 with the shifters added instead of just the laser recievers.

    Thanks. So basically the question is whether adding the ZR3 heads into the control box is going to turn my SR7 into a SR7+. I do have the ZR3 heads in hand (box is still factory sealed) - but would rather know before I open the box (right now I should still be able to return them to Escort).

    I mean the escort website indicates that the ZR3 works with the SR7 (i.e. they did not say SR7+) - so it should really work. Still I will call Escort Customer service on Monday and hopefully will get a straight answer from them.

    If not - I might very well return the ZR3 - give up on the idea of integration and just get the Blinder M25 (which I was debating anyway).

    Thanks again.

    The SR7 is upgradeable with the ZR3 you just change the control module and add the new shifter (jammer) heads and you ready to go. Make sure the heads are level and straight. You need to place the heads so your headlights and license plate are within an 18" radius of each head.

    Also, in case you didn't read the instructions like I didn't read them. Hit the mute switch twice to kill the jammer while it's activated.

    Oh, the bubble on the heads goes up.

    Thanks Erick and RacerX
    Based on this I will in fact stick with ZR3 and will just have to decide whether i go for the regular or the enthusiast set-up.

    The 911 has a relatively narrow nose, no chrome and is really sloped (inlcuding the lights). Headlight to Headlight the car is about 50 inches across (62 is the width of the entire car)

    On the downside - I do have a frontplate (which I will cover with Lasershield and I will Veil the lights).

    So 3 heads in front and a bare ride at the back or only 2 to the front and at least some mediocre jaming on at the rear of the car.

    Decisions, Decisions, .......

    Meanwhile - should the shifters be installed at the same height as the plate or as low as possible ?

    Thanks again
