Garmin GPSMAP 545S 5-Inch Waterproof Marine GPS and Chartplotter with Dual Frequency Transducer I "upgraded" to this 545s unit from the gpsmap 478.. Simply because the connection on the back of the 478 were not up to the task of saltwater spray for both the XM antenna and power cord... I wish i hadn't. Yes, it's a bigger screen, BUT.. you have to push many more buttons to get to where you want to be on the machine. There is not a simple waypoint entry.. while cruising on a vessel. You have to make multiple entries to save it. The worst loss is of the NOAA forecasts that were on the 478. Now all you get is a little graphical icon and current conditions.. Come on Garmin... make this a useful piece of equipment instead of a boat anchor.
