I suggest you call Hopkins direct if you can't get it to work. They have a good service department. Our Allegro is only 30ft long and had no problem receiving the wireless signal. I did have to put the sending unit up in the window just below the rearview mirror and the reciever high on the dash. I also have a rear window which may have helped with line of sight. Try moving all the components closer together,ie: a second car nearby, and useing the test button see if it is a distance problem. Hopkins will need to know that when they make good.
Hope this helps.
