go into your sonar settings and the look for installation at the bottom and press ent. then scroll to transducer and press ent. then match your transducer. you should a silver tab next to your blue knob of your transducer cord. then see if comes back up.
if not try going back to your overlay

if does work try this;

HDS settings when using Network Sonar
Network sonar enables Multiple HDS units to share a single sonar source, or to change all units in the network from source to source. There are a few settings that need to be changed so that network sonar does not change where the unit is looking for its sonar overlay data (depth/temperature). With network sonar enabled you are only able to display one set of sonar data at a time, if you wish to show the depths and temperatures from different transducers network sonar must be turned off. *Running two transducers at the same time can cause cross talk interference.
There are two ways to network HDS units and use Network Sonar:
� Ethernet only: Allows sonar data to be shared only while network sonar is enabled. When network sonar is enabled on both units you will only be able to use one sonar source (data from one transducer) at a time.
� Ethernet and NMEA2000: Allows sonar data to be shared via network sonar. Also allows sonar overlay data to be shared via NMEA2000 network when network sonar is disabled. (Can show temp from one unit on another)
To enable/disable Network Sonar:
Menu>Menu>Sonar>Network sonar. (This dot must be highlighted in both units before network sonar will function. To disable it only has to be turned off on one of the two units.)
Setting the Temp and Depth source:
Setting the temp and depth source will allow the unit to display the active sonar data while network sonar is enabled and to display its own data when network sonar is disabled.
Menu>Menu>Network>Data sources�>Sonar>Water temperature>Menu>Scope>Local
Then set the active source as HDS-# Sonar [This Device]
This must be performed on at least one of the two HDS in a network; it can be done to both.
Follow the same procedure for Depth.
