ST60+ Speed Display

[wingover]

Started the boat today and got --- on the speed display and a message on the ST70 I got "Speed chapter not available"

Tested the sensor according to airmar and it works. I tried a factory reset but still nothing beside these 3 dashes. Not speed or temp showing.

Anyone had the same problem?

My guess would be wiring or connection problem if you have established that the transducer is ok. The messages you are getting basically confirm that the data is not getting to the ST60 & 70 units. (Rather than a fault with the units themselves).

I concur, Doctor.
