Question about Necvox RE-8169D 8 All-In-One Motorized System Car Video Player
I have the Necvox FD6569 screens fitted in the back of my range rover sport, when the ignition is on and the screens are plugged in they interfere with the FM radio signal even when the screens are switched off, if the ignition is off the FM reception is ok but as soon as the ignition switch is turned the interference occurs, any ideas?
When you say "the ignition switch is turned", does that mean the engine not running or running?

most car radios have an interference power filter, consisting of a special arrangement of a coil and capacitor. It is packaged in a plastic enclosure about 2 inches by 1 inch by inch. This filter is designed to reduce the interference caused by the system wiring picking up RF noise from the engine controls. In your case, when the switch is on, your video device (which can produce much RF noise) is interfering with the radio. Have the radio checked for the presence of this radio filter, and if it exists, try using two filters together (can be purchased at Radio Shack) wired in series.

Hi 24 seven,
It makes no difference whether the engine is running or not, there is interference when the key is turned to position 1 (ignition on) or the engine is running, the interference only stops when the key is turned off (position 0)
It seems to me that when the key is turned to position 1 or further power is supplied to the screens even when they are not in use as if they are in standby mode and this is when the problem occurs.
Regards Robin
Thankyou I will try this and post the result.
