I installed my F90BT and it worked great, then i tried to install the 3.3 bluetooh update. it didn't work, so then my xm, address search and bluetooth options were all grayed out.

 

I took the thing apart and check for possible the hardware bypass not grounded good enough.

that didn't fix the issue.

 

 

Please HELP!!!!! I just want my Navigation to be fully functioning!!!
