I have AT on my bass and big water boats. My brand new one freezes every 2-4hrs of use for 10-15 seconds then comes back normally. Overlays stay. Depth/forward range and x/y axis lines stay. just loose the sonar (black). Voltage not the issue as dedicated 10g from my new ionics 125 lithium feeding just my sonar on board. voltage showed 12.8-12.9 all day yesterday and froze 3x in 11hrs on the water.
Wonder if anyone else has this issue. The AT was just installed. I have never seen this on my bass boat unit.
Thx
