My edge came with the factory mp3 SYNC 6 disc in a box and installed is a factory looking aftermarket navigation unit, unsure of the brand but the OS is Windows based and nav software is OttoNavi. All controls and features work except for the headphone jack and usb port in the console. But my biggest booger is the poor antenna reception. Does anyone know of other connections to check besides the one in the dash? Or could it be the unit itself.
