problem with park cam
 

I install a park cam on my stock navi using the avelectronic and i have a problem the screen has very bad refresh rate.
The hks camp on the same device is perfect.
my can is pal there is any way to change in my navi menu from NTSC to Pal??
there is any possibility for another issue?
thanks

i forget to tell that the cam is pal and not ntsc

nobody knows if my 8 need a pal or ntsc park cam???

not sure why you don't see this, but it has nothing to do with your 8. as you stated yourself, your avswitcher works fine with your screen.

your avswitcher converts the video input into a usable signal for your nav screen. so obviously the problem is between your camera and your avswitcher. why not check with the manufacturer? and FWIW, if you already know your pal camera is not working, it seems pretty clear to me that that's the problem and you ought to go get an NTSC one..

yes i am gonna order an ntsc camera know to check it.
i communicate with avelectronic and they told my that all the 8s need ntsc tv system to play.
