Was wanting to put new Garmin 93svUHD on dash, run the the GT-54 on a jackplate mount and a in-hull for hi-speed sonar (GT8W-1H)? Garmin says it's not doable with the splitter because the GT-54 is a 3 in-1 so unit won't know which transducer to use for sonar so it will get an error message. Anybody have a way around this? Almost ready to return it and get a 'Bird. I have a 2010 Nitro Z-9 and external mount will have to be way up under the back to get sonar at speed.
