Which is the better GPS? Garmin Rino® 530HCx or Garmin GPSMAP® 60CSx. I know the basic differences between the GPS is that the Garmin Rino® 530HCx is a 2-way radio and the Garmin GPSMAP® 60CSx is not. I'm more interested in finding out which one is a better GPS? If the Garmin GPSMAP® 60CSx is a better GPS, than I wouldn't mind carrying a separate 2-way radio, but if the Garmin Rino® 530HCx is just as good as the Garmin GPSMAP® 60CSx, then I'll buy it. Besides the having the radio on the Garmin Rino® 530HCx are they basically the same GPS? The price difference is about $100.00 more for the Garmin Rino® 530HCx, is it worth it or not? Thank you!
