I installed our overhead dvd system into our 2001 Suburban LT w/ a sunroof without much trouble over the weekend. Wireless FM Modulator plugged into audio of DVD player and sounds great picking up most surround sound...however...I noticed this morning while traveling and watching something that we have a very high pitched buzzing sound that becomes higher pitched the faster you go. While sitting still @ a stop light or sign you cannot hear it. Does this have something to do with my power supply to the FM Modulator or is there another fix. Thanks! This is my first install and I'm not a car stereo guy so thank you for any help! BC

Most video systems require both a inline power line noise filter installed inline on the ignition power wire to all the components in the video system. You may also try installing a RCA ground loop isolator between the FM modulator and anything else on the audio lines. Ground all your components to one source of the car body that is clean and paint free.
