My recent purchase ( GW228 ) came with a Garmin 498... I am struggling to get it to initialize but am certainly not giving up on it. I have decided to put a Lowrance sonar/gps on it as well... I don't know if I can justify radar but I definitely want the high end bottom imaging transducer as well as the 83/200 mhz one.. Also want a built in maps/charts. Was wondering if anyone had any ideas or suggestions.
