Been at the dealer this week and enabled a rear cam on uConnect RHB 430N infotainment unit. Getting fuzzy / flickering image?

It shows just fine when I stream the same video signal through WIFIAV (video over WiFi, from the same source, powered in parallel, video out is feeding the two).

When camera power is disconnected, blank screen w/Check entire surroundings' title displays just fine. http://www.youtube.com/watch?v=CH0oTXnzpn0

Brought another video source to the vehicle, by looking inside confirmed it has a PAL chip if that might be relevant. http://www.youtube.com/watch?v=4UfC4-ZTr9Q

Same split fuzzy image on the dash WIFIAV

but nothing wrong via WIFIAV WIFIAV.

What the issue might be?

It could be a video format issue. If your infotainment unit is configured for PAL format. Your backup camera may not be. Is there a switch on the camera unit to change format.

Comparison of formats:

Video Bandwidth: NTSC 4.2MHz Pal: 5.0 MHz

Vertical Freq: NTSC 60Hz Pal: 50Hz (this could explain flickering)

Horizontal Frequency: NTSC 15.734 kHz PAL: 15.625 kHz (this could explain shakiness of image and double images)

Lines/Field: NTSC: 525/60 Pal: 625/50
