Hello,
I plugged a module ipod charger plug on the CD.
I have a GPS 16 / 9, the DSP, and the sound HiFi option 677.
On the amp in the trunk, I have a coaxial connector.
I have taken over three and six taken over between the seats.
I tried to connect the module by the coaxial cable and the 3 wire, I have no sound.
I am forced to connect the module to take 6 wire and 3 wire for sound.
How can I do to get sound by plugging the coaxial connector?
 
Your system works properly using the 6 wire cable? That's interesting, from what I've heard, it should not work on DSP systems. If it's working properly, I wouldn't worry about the coax connection, I don't think there's any advantage to one or the other.

Your post is a little unclear on how you connected the coax, and details vary with various adapters. First confirm your adapter as compatible with Nav systems, some are not (don't know why). The adapter works by appearing to be a CD changer to the car's audio system. DSP changers/adapters connect directly to the amp via coax. Non DSP adapters connect to the radio via the 6 wire cable (only 3 wires are actually used). Power is supplied via the 3 wire cable.

So DSP adapters would either connect to the coax cable where the CD changer would normally connect, or connect directly to the amp, not using the factory coax. They get power from the 3 wire cable. These adapters should be plug and play, the connections are straight forward, once you find them. If it's not working, try looking for trouble shooting info in the instructions, or you may have to try to reach technical support from the manufacturer. Good luck!

Incidentally, even the non-DSP 6 wire connection must still be digital, there is no analog way to control the changer and transmit text data and audio signals over just the 3 active wires.
 
I find the sound of the iphone is worse than the CD.
That's why want to use the digital connector.

The adapter for the iphone that I bought has a 3 wire connector, 6 wire connector and one ​​connnector digital.
I connected the 3 wire connector and the digital wire directly to the amp: no sound.
I connected the cable 3 wire and cable 6 wire : it works.
I have the DSP with the curve, the navigation screen 16 / 9 and 10 speakers.
 
Since the 6 wire audio is poor quality, I would not say that it "works". With DSP systems, the coax to the amp is the correct setup, can't help you as to why it doesn't work. Sorry mate.
