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) ?
