i just recently purchased another f700BT for my girl's Mazda 3 and after finishing the wiring and everything, i go to pop it in. . . and im not getting ANY sound from it. not even from the button presses, let alone from any audio source. so to make sure i didnt mess up the wiring, i connected the unit to my car (with my 100% i know it works wiring) and . . . no sound, so i take MY deck and connect it to her car (with previously mentioned wires). . . and lo there be sound.so now i know for a fact it's not the wiring, but the deck. anyone else have this issue? any ideas? would a FW update somehow maybe work?
