I have looked at all the question and answers with no luck. I update the firmware on the Evo-one, re-programmed every way possible with different firmware’s, re-programmed the mycar module, I’ve used with and without the little harness that comes with the mycar module, see if the Evo receives a lock/unlock signal while on (nothing), checked if the module is plugged in the right slot. I send the signal from the mycar app, turns green and then red for every option. The app shows signal, battery voltage, gps location, but it won’t accept any command. Please help!! (Can it be a defective device?) It worked before and all of a sudden stopped working.
