Furrion BU camera issue

[Old Yankee]

My friend has just installed a Furrion camera on his Arctic Wolf, it was prewired for it. Camera works fine, with TV turned off. Once he starts the engine, monitor is blank. Same result with headlights on, or in auto. Camera has blue light on, when no display. TV is a 2011 GMC Terrain. Any ideas?
Thanks

Did you sync the camera using the cable? Our Furrion observation camera sync'ed out of the box to the screen but would loose lock until we sync'ed it with the included cable.

Wonder if the TV engine is causing enough signal interference to prevent it from working. Try moving the display closer to the camera to see if it picks up. You may need to reorient the antennas or get an extender for the camera antenna. Antennas work best if they are both oriented the same.
