I've installed the Blinder M25 and Cheetah wireless fitting kit. To test it, I used the remote key fob to see if the stealth mode is working and it is turning it on and off fine.
I tested the parking sensor by putting my hand over the laser jammer head and audio node went off and worked fine first two times. On the third try, it is not working. So I don't know what the problem is. Wiring is fine, LED on the node of the jammer turns on and off fine.
