i have an iva-d310 in my 03 g35 coupe(6mt) and i have sound from the radio, but when i try to play a cd or use my i pod...it will read off the track and folder...but no sound will come through the cd or ipod...can someone help me with this...never had this prob before...also i do have the pac-tr7 hooked up too.. if anyone has any suggestions or has had this problem with this screen or any other screens any information would much appreciated...thanks

 

I'm guessing you just installed the d310, the blue wire on the wiring harness should be connected to the blue white wire as the blue wire (pwr ant) is also the amp turn on wire.
That's why you only have sound when the radio is on
