I know this post has been a long time coming, but I would like to extend a big welcome too Beltronics and Escort.
Thank you for joining!
I have been using your zr3 and now 4 ever since they were available in RSA on my cars and I have had no bad experiances, thank you.
Just one question, would the zr3 transponders work if plugged in to the zr4 control unit? I hit a bird the other day at about 100mph and luckely it missed the tronsponder by about four inches. As I still have a full set of transponders for a zr3 laying around, I was wondering if the need arose, could a damaged one be replaced with an older one?
