Disappointing Satellite Imagery - Vision card is waste of money.

Summary: Nice GPS. Quick to setup and easy to use ...but... BEWARE.... The BlueChart g2 Vision is a waste of money as the HIGH resolution satellite imagery is ONLY for selected ports and not for most other areas ... VERY disappointing as this is not made obvious in the sales literature.
Summary: The Garmin GPSMAP 546s is leagues ahead of my old Garmin 188 GPS. The reason I did not give it 5 stars is because my old 188 had a feature that is missing from the 546s. You could select a hazard and assign a distance ring around it and if the boat went inside this range ring you would get an alarm.
Summary: I have been out of boating a while so these new things just blow me away.. I always used a compass but this GPS is great, It takes a little getting used to but once you master it WOW.I am new here in Fla so I haven't Mastered the land marks,but who needs to with this..
Summary: After reading reviews and descriptions, I was prepared for the graphics to be not much better than my old 498 unit. I was pleasantly surprised to find the graphics are clearly better than the old 498, even without the add-on detailed map purchase.
