I tested the camera in the car this morning and no joy.
Started working my way thru the system and ultimately found that the TraqDash unit that controls the camera operation was only outputting 1vdc instead of 5vdc. No surprise that the camera wasn't working!
I went to the TraqMate website and found that they announced in July that they were halting production and unfortunately, they appear to be in the process of closing down. The website said they will still provide repairs and support so I sent them a message explaining the problem.
I'd rather not change the data system, so just in case TraqMate can't repair the unit I bought a 12vdc to 5vdc convertor module. I can tie the input to the 12vdc power going to the TraqMate and then wire the 5vdc output direct to the camera (bypassing the TraqDash).
This should fix the problem one way or another.
