2003 Trailblazer EXT DVD FM-Modulator

Anyone know which wires on the Factory installed DVD Entertainment Unit, I can attach a FM-Modulator so that the sound comes from the car speakers and not only via headphones.

Thanks

why cant you use a wireless fm-modulator ? You should be able to just put a Y cable in line and put that to the wireless,i hope this helps

I don't want to use the wireless one as it doesn't work that well... that is how it is set up right now and the sound keeps cutting in and out. So I figured if i just hard wire it into the system... it will be permanent. Thanks for the suggestion. :)

On the back of the dvd player there should be a pair of audio out RCA jacks. Put in  Y-splitters on the RCA audio out (L&R), and install the modulator per the instrucions. Add a switch to the modulator 12v power line so that you can physically turn the modulator off when it is not needed, that way you still have the option of using the wireless headphones or the radio. If you do not want the wireless headphones at all then just plug the RCA cables into the back of the DVD player (without the y-splitters) and the other end  into the modulator per the manufacturers requirements. If the audio wires coming out of the dvd player are not the RCA style, then sorry I cannot help you on that one. Hope this helps more than it confuses.

Thanks alot sjpsfp. That does help. I never thought about the switch. Thanks.
