    Question Sidescan only working one side, any ideas?

    I searched the forums and read the first 6 pages of the Garmin forum. I cant seem to find the answer.
    I installed a GT56 transducer for my 122SV and upon fireup today, Only one side of the sidescan is working.
    Any info or ideas would be greatly appreciated.
    Thanks,

    Make sure one of the connector pins didn’t get bent and that the connector is seated all the way in the backplate. If you have another unit, connect the transducer to it to see if it’s working.

    Appreciate the ideas. The transducer was used prior on my kayak, so I know it was working fine.
    Ill double check the connection.

    Where is the transducer installed? Only reason I ask, mounted mine on the transom and the lower unit think is blocking mine.

    Mine is mounted in the very back middle of the boat. Used the exact same location of the previous one and didn't have any issues.

    I don't know if Garmin has this feature, but Humminbird has a setting that tells your unit to only scan left or right as an option. Maybe you have it and accidentaly turned it on?

    I have the same issue from my GT 36 on the left side and only at frequency 1070. I just converted from Humminbird to Garmin. I have 2 -106s. I had to buy the combo transducer of the GT 8 and GT 36 so I could get high speed 2D with the GT 8 glassed in the bottom of my bass boat. Garmin does have excellent support. I spent an hour on the phone while on the water, but we could never resolve my issue. I’ve sent them a picture of the problem and the GT serial number. I’m waiting on a response. Have you tried garmin’s support?

    Just as aside…I love the livescope, but so far the down scan and sidescan aren’t even close to humminbird. I’ll continue to work on my down-scan and side scan settings. Hopefully I will get better screen images.
