I just had a navnet vx2 installed on my boat. Everything seems to be working ok but I cannot get the sounder to give a digital depth or a temp reading in sounder mode. It will give me a depth contour reading though. I CAN get a digital depth reading while in plotter mode. Anyone have any idea how I can get this to work? :questions Not sure of type transducer but depth and temp worked when hooked to old unit. (Sitex 106) Thru hull transducer and can't find markings on wiring or ducer to find out what transducer it is.
