Sony CDX-GT710, no sound from CD!

[Cochise]

Hello all,

I recently bought a Sony CDX-GT710. After installing it myself, the radio tuner works perfectly. However, when inserting a CD, it will play it, but I get no sound from any speakers. I'm thinking it must be an issue with the unit itself and not an issue with my installation, since the tuner works fine and sounds great. I have tried about 5 different CD's, some MP3 CD's, and a regular CD-R that I burned. Same result on all of them. It shows the track duration, so I know it's playing, but I get no sound.

Also, I have not tested the Aux input yet, so I don't know if the same thing is going on with that.

Do I have a defective stereo? Did I miss some setting that will give me my sound back? Any help is appreciated. Thanks!

did u check to see if it has a tiny screw on top of the actual head unit?

i know theres a few where u have to remove the screw before playing cd's.

Are you using the speaker outputs or using an amp to power your speakers?

If using an amp, sounds like the antenna wire is being used to trigger the amp and not the remote wire. Need a lil more info on your setup.

I'm running a stock Infinity amp in my 1998 Jeep Grand Cherokee Limited. Not sure about a model number.

Wait a minute, I think I found the problem (thanks to you, Mr. C).

So to find out which wires went where, I downloaded a PDF from InstallDr.

The PDF was too big to attach here, so here's a screenshot:

Notice Pin G. It's for the "Power Antenna/Amp". It says "use for Infinity Radio". I know for a fact that I connected that wire without thinking.

Would cutting that connection solve my problem?

UPDATE: Looks like I need to connect pin G's wire to the blue/white wire instead of the blue one on the Sony. I remember that blue/white wire saying Amp on it.
