This is a must to be added to your FitCamX. The price was very reasonable. I used a multi meter and found a fuse for acc and battery, allowing my camera to power on when something triggers it. I was able to get it installed by taking my time with the cable. The instructions provided were perfect.
It's definitely one of the best purchases made. I only wish I had purchased it when I originally purchased my FitCamX, but I have it now and my car is armed with front and rear cameras!
I just receive the wrong fuse cable, but I got a good support from company. They sent me a correct fuse cable.
