I just completed the install of my F700 with the GEX-P10HD HD tuner. For some reason, there is no sound when the source is set to HD. The unit tunes in HD stations just fine (shows good signal strength) but there is no sound.

When using standard radio (AM/FM) the sound works fine so I am sure it is not the speaker connections. Also since the head unit tunes HD stations ok I dont see how there could be an issue with the way the GEX-P10HD is connected.

IS there something wrong with my HD tuner or maybe the head unit or did I do something wrong?

Anyoone got any thoughts?

[EDIT] BTW I did the hardware bypass (moving the mute wire and gounding it and the pb wire) maybe I did something wrong here??

Thanks,

Steve

Are there 2 IP-Bus jacks on the HD unit? If so, try plugging into the other one. That's often been the solution for the Sirius tuners

+1 the IP-Bus connector on the back of the AVIC is blue, plug the blue end of the IP-Bus cable into the AVIC, the other end of the IP-Bus cable is black, make sure you plug this end of the cable into the black connector on the HD box, the blue connector is for connecting other componets

Yep that was it.
