CANNOT READ ANTENNA

I had a similar type problem where i have a lifetime subscription and my XACT VISOR XTR3 unit had a faulty power connection that was driving me nuts. i decided to try and swap out the internal receiver component with a new unactivated unit i bought on ebay. (all the types are out there and pretty cheap even for new)

in opening the new one up i found the only difference from unit to unit is the receiver brain inside the unit, and it is relatively easy to swap out the brain into the body of a new unactivated unit. just four small screws and carefully pull the brain out of the long multi-pin connector. i put the old brain into the new carcass, screwed it back together and it works like a champ. just have some patience in figuring out exactly how your particular unit comes apart, and you will need small screwdrivers and either a small allen-key set or torx set - my old unit had the allen-key screws on the outer case and the newer one had torx screws.
