Hi. I've had a D3 for a few months with iPod and bluetooth connections and everything worked perfectly fine with no issues for months. I never messed with any of the settings. However when I got in my car (08 Scion XB) one day the sound didn't work at all for anything (GPS, iPod, radio) but the subs worked perfectly fine on beat. Then the next day the sound came back, but then cut out in about 15 minutes with no static or anything with the subs still working. All the functions still work perfectly fine, just without sound.

I've searched the forums for an answer but I haven't been able to find one for the situation. Please help!

Sounds like your speaker harness at the back of the radio isn't pressed in all the way or the spliced joints to the vehicle harness adaptor are coming apart (or the adaptor harness is not connected to the vehicle harness correctly). I would take the radio out and check the connections.

Thanks for the tip. I ended up swallowing my pride and taking it to an audio shop. It ended up being the wires for my right rear speaker had wrapped around the speaker basket. A safety precaution for the D3 shuts off all power to the speakers if something is not grounded properly.
