Garmin VUS004R-New York U.S. Northeast Coast BlueChart g2 Vision SD Card

I loved the concept of the G2 card, however it really falls short. First off you need to load up some info. You need to load in the depth of draft, height of the boat and distance from the destination location that you wish to end up at. The satellite image overlays are too dark to see the channel and buoys especially in the daylight, let alone while wearing shades. If you lighten it up to the point in which you can see the channels etc. then the overlays really cannot be seen, so what's the point. When you zoom in on the satellite images, they are very pixilated at medium to close range. As for charting you need to be in deep enough water for it to even start working and this depth needs to be on the chart where your starting point is. It will only navigate to outside of your destination. If the address of your destination is a land address then it will not work, Hmmm a lot of the locations are land addresses. It will not work when you are between two land masses, such as the State channel which is a channel on the island here that runs a few miles long and is approx. 300 feet wide and averages 25 feet deep. When I finally got it to work the few times it worked right, the route that it displays is a route that is based upon the depth that you chose, for me it was 3 feet for my draft. It routed the boat from point A to point B in water deeper then 3 feet. The big down fall here is that it gives no regard to channels. It will take you straight across the bay in water that is 3 feet or more according to the chart. This does not take into any consideration of any fish nets, underwater obstacles, and sunken boats, broken poles, trap marking buoys etc. I prefer to run the channel just for the safety that it provides and even then you know how some channels can be. Now I did not just pop the software in and play with it for an hour. I worked on this for over 10 hours of my time. I was on the phone with Garmin 4 times trying to resolve these issues. They were very, very helpful but there were some of these issue that I state that they were not sure of why it would not work either, especially the channel issue. Unfortunately software is software and sometimes it just is not tweeked enough to do what is expected I am sure in time, it will get it tweeked 100%.So back to the standard way of adding turns and routing thru channels is what I will do until they make some major advances in this software. I am sure that the newer versions will fix all of this. For me, running outside the channels where the water is very shallow with no regard for underwater obstacles is not for me. How about you?
