Hey i have a 7" lilliput in my dash . when my car is in the off position with my screen on everything weorks great but when i turn my car on i see interference on the screen. its like small little lines. when i revv the car i see them more and more. i have it connected 12v egg to my cig lighter. is there any way i can connect it to my DSATX power supply to get a better or cleaner signal???
