Does anyone else have a problem with their HB Si locking up? It will be working fine @ 2.3 mph then it locks up and won't scroll any more. Stays that way for 3 min or more. Sometimes it helps to shut it off and turn it back on. I have up dated the software. I have tried speeding the charting speed up and down, nothing. Between the locking up and the depth reading going from 12' to 786' I am almost sorry I bought the thing.
