Hello,

I recently had the 150Bh installed w a nD-BC6. I updated the firmware to 1.4. They didnt bypass it but I have the thing on eBay to do it easier. I'd like to view the camera while driving & found the option in the map mode to split the screen for camera & map but camera half is blank. Works fine when I put my vehicle in reverse. Any ideas?thanks

You don't have your camera powered from constant power. Take it back to the installer and have them fix it.

Yeah they most likely used the power coming from the reverse lamp to power up the cam.
