Buddy just bought a brand new triton from a dealer 4 hours away, took the boat for its break in voyage and have an issue with the graph. I’m trying to help him troubleshoot before he has to drive 8 hours to get it fixed. So the unit is in dash and is gps,di,si . The only thing working is the gps stuff, no depth reading and no graph movement at all just white screen for all the 2d and then a frozen screen shot of the si. It almost seems like it is frozen in simulation mode. So I confirmed it is reading the transducer and I did a restore to factory settings and nothing. I am assuming this was a factory triton install. Any help or ideas of what might be the culprit? Base map, speed and route tracking all work fine, again brand new unit. Thoughts?
