Yes!
I installed BC30 cameras in both of our cars. You must use the power cable that comes with the backup camera (not the cable that comes with the GPS) because that is how the wireless feature works.
Use the power cable that comes with the camera in the car with that specific camera. (I tried using the cable from the first camera when I installed the second camera and it didn't work. I thought I had installed the camera incorrectly. I tried the cable that came with the second camera and it worked fine. Don't know why that is the case and I really don't care.)
Great cameras! Great safety feature.
