OK, I got my Monitor/DVD installed yesterday. I have the MTV 10.4 TFT and Phoenix Digital DVD. I bought the FM modulator from frys. The guy told me thats the best one. My problem is, I have this engine noise when the FM modulator is turned on, If I turn it off the is no engine noise. The other problem is that it weakend my signal of the radio station. I used to get 94.9 and so on here in the valley with no problem, now I only get 97.7. I unplug the modulator and everything is fine. Any suggestion on the best way to fix it? I thought of gettig the noise filter, but it will not fix my signal problem. I was thinkig of buying another FM modulator, but I dont know which one. Also I was reading some forum and they kept on talking about their chevy or GM having the AUX on the radio.. any idea?
