Bought the 12/9 boat in a box from Tackle Warehouse this past December and just got around to having North Texas Marine attempt install. Both units, the 9 and the 12 will recognize both the trolling motor transducer and the Totalscan transducer mounted to the transom. However, neither unit is receiving information (sonar, side scan, nor down scan) from the totalscan transducer. They will both pick up the info from the trolling motor transducer.
We thought maybe the totalscan transducer was broke, so they brought 2 different totalscan transducers out, hooked them up to both units, and still nothing.
Any idea what might be going on here? North Texas Marine service department is now suggesting that we just go back to a separate sonar transducer, structure transducer, and the box (whatever it's called), but it doesn't seem like we should have to go backward in technology to make this work. Also, both units have the most recent software updates.
