Try these settings! Mine works like a charm. And don't forget to perform the update. You can pull it from the Lowrance website. It's super easy!
Here are the correct settings for the HDS Units:
· Auto Sensitivity
· Range – Auto
· Frequency - 200 kHz
· Chart speed – 2x
· Fishing mode – General
· Ping Speed - 15
· Noise reduction - low
· Surface clarity – off
· Palette - 13
· Transducer - make sure you go to “Installation†under “Sonar†settings and select the correct transducer.
· Network – make sure you go to “Data Source†under “Sonar†use the temp from the Lowrance unit, not Global (via network).
Good luck!
