There is no switching or changing of menu settings because the wires going to the 2d piezo in the stock SI xducer have been disconnected (in the AS SIDB Y cable) and re-routed to the US2 piezo ...

Maybe I missed something, but this appears that there will only be digital depth available when the TM is in the water, and no depth readings available when running on plane?
