Bad radio reception DVD related?

[glassman66]

My Hummer service advisor said that my bad AM reception might be because of a audio switch that has the sound go through the factory system.

Any idea where that switch might be?

I thought my DVD system was factory. I could be wrong the truck is new to me at 30K.

I come to find out that there is a FM modulator for the DVD, I turned the switch off after I found where they hid it, and presto AM is back. Mine was in the left side of the glove box.

FM modulator, everytime I hear that I say it like Marvin the Martian off of Looney Toons.

glassman66,
If they installed an fm modulator in your system, you will definitely need to turn that off when listening to other stations--fm or am as both can be affected when the modulator is on.

...crappy antenna on the '03s. I had the same problem...

Wonder if you can change the 03 antenna to the 04 side plate antenna if that would work better ?

Mine is an 04. I think the FM mod was added aftermarket by the previous owner.


Once that was off the AM is perfect and the FM is better. The FM was not tto bad before. I'm a Talk Radio whore so I needed my aM back.
