Have tried to connect both the Dice Duo and USA Spec iPod adapters in my 03 4.6is with no luck. Using the stock CD changer location in the rear of the truck. I have the 6 pin and 3 pin connectors so it should be straight forward. I can get all of the controls to work on the head unit, but get no sound at all. I did get sound briefly on one of the two USA Spec units I tried, but it only worked for a minute. I've tried everything I've found on this site many times to no avail including the battery disconnect.
My question is, is it possible to have the 3 pin, 6 pin, AND the dsp coax cable? I have an extra small, press in connector that was also plugged into the CD player. I'll go take a picture. I think I'll try the USA Spec DSP model, but that will leave the 6 pin not connected to anything. Does that makes sense?
Any ideas? Thanks!!!!
