I got the 2008 charts back from Garmin last week. None of them were the right version. I sent them two Bluechart g2 and got back one Bluechart g2 Vision and one "Classic". The classic one doesn't even work in my unit. (GPSmap 620). I've talked to Garmin and they said they are going to send out a new card tomorrow.
The strange depth contours are gone now. Much better.
I tried out the Vision chart this weekend and no, it is not worth the extra money. The only useful extras is roads on land and maybe aerial photos, but you can just as well bring a cheap paper map. The satellite photos painted on land just makes it harder to distinguish from shallow water, at least on a 5'' screen in sunlight so I turned that off pretty quick.
3D stuff? Who is the target audience for that?
I tried the auto guide to a destination 7-8NM away, fairly simple navigation. A moderately experienced navigator could eyeball a safe route in under a minute with paper charts. With the right navigational litterature at hand, a slightly quicker route (which the gps would not know of) in maybe 5-10. After watching the spinning thingy for 20 minutes, I grew tired of waiting and turned the unit off. Maybe it's the charts in this area or the 620, but that feature is pretty much useless for me.
