How do i connect a mp3 player to a jvc kd-g331

Here is the installation guide for a KD-R200. For car specific, you would have to reach out to car dealership

I am thinking you can connect with a 3.5 m m. Jack, with left right input jacks connected to it. Going to give it a try. Also might try the phone the same way.

The wiring diagram is on the second page of the installation manual.

It should be blue/white.

Go to jvc.com. search for the model and download the Instruction book

turn the unit off, while on standby push and hold the select button

Connect the brake wire to the ground wire when installing it.

Unfortunately, you can't. I have the same deck, and it has no aux in capability. The S5050 is simply a CD player, not even an MP3 player.

The JVC-G331 should have an auxilary output on the Back (red & White) run two Stereo RCA cables from this output to the input on the amplifier, then you're ready to go! ;)

Oh yeah, make sure and run the RCA's on the opposite side of the car as the power wire (most likely 4ga) or else you could hear interference.

Hi, did you fix this problem?
I'm having exactly the same issue myself.
