Anyone use a GPSMAP 620? I am looking to install my first chartplotter and am quite taken with the 620. Seems to be a smaller portable version of the 750 (without the add radar option) with the added benefit of dual use as a car satnav. The fact that it has its own battery means that there would be no need to install a second station down below for passage planning activities. How good is the touch screen? Any concerns over corrosion of the contacts on the unit and mount? Any user feedback would be useful in making my decision. Thanks
