Garmin BlueChart g2 Vision Vancouver/San Diego Saltwater Navigation Map MicroSD Card - Detailed Marine Charts for Boating, Fishing & Sailing in Pacific Coastal Waters

I have only used the g2 vision card in my cruiser once so I am still learning how to use it. I use this in the Sacramento Delta mostly and I found it will create an auto route in the main deep water channel but will not create an auto route in the various sloughs in the Delta. Other than that I love this product, easy to use and gives you defferent ways to view the water ways.Was not the latest as was advertised. should have been 2017 but was actually 2015.When Garmin updated its software for my 7610 chartplotter this SD card is no longer authenticated and I will not be able to use it in 90 days.I purchased the chart plotter Lowrance Elite 7 HDI, and with the above Garmin Blue Chart g2 Vision Vancouver / San Diego, as this Blue Chart is not compatible with the Lowrance Elite, I have no use for the Blue Chart, and like to return it! I do need NAVIONIC Charts, and would like to exchange it for a compatible Navionic chart for B.C. and U.S wters !Please inform me, what I can do.Otto LukatI had problems with the order two years later and the vendor went out of their way to make it right.I just tried to log into Garmin and update. Was told I purchased a pirated chip. No recourse for me other than buy it again somewhere more reputable.This Bluechart SD card does nothing. When we insert into the Garmin GPS440 nothing changes.This was the largest mistake we made. This card made absolutely no change to what we saw on the screen.Very disappointed.Amazing graphics and features. The auto guidance feature seems to work very well all over the Puget Sound. Worth every penny.
