Caty! No problem with g2 Vision charts too. I do not have not-g2 Vision version for my region and so I use g2 Vision!

Device ignore 3d, aerial and auto guidance simply! Only one moment that g2 Vision is more expensive
This unit have the same small problem with both format with not-g2 Vision so as to g2 Vision in map control menu. It is not significant but the best way delete some sub-maps. We discussed that in one of old thread...

Ok, thanks, I don't remember, I simply looked at product page and Vision are not listed.

I edited my previous post and I added remark about difference in cost of both these maps I think that is "at product page and Vision are not listed" from.

G2 non Vision are smaller too

easy rider, your device support only one gmapsupp.img file with max size 4GB on micro SD (size of microSD may be up to 32 Gb and microSD must have HC specification only). You can use Mapsource but some Garmin maps format like BlueChart G2 and G2 Vision do not have installer for Mapsource. Advanced user may to make Mapsource installation from any maps but you must read this forum from from beginning to end to become it.
In you case you must use gmaptool to combine maps simply...

You are absolutely right- I had to start from the very beginning, what I did, to grind down all knowledges that I miss, but, somehow, I came across an ocean of somewhat controversial and vague info, which I can not select and systemize to the best of my ability/ if any/, having grain, not the straw to avoid situation like this, ie, to make bricks without straw I tried to ask simple questions, awaitng simple answers to match my simplicity,anyhow. Here, by your courtesy, I learned more than months dedicated to this matter.

Catymag, thank you for reverting. As for the link,you posted, I already followed in advance yesterday, as if I knew for the gentle and helpful reproach, that was in store for me in Giomen's one, I'm thankfully reading now :-)

Once more, thank you all guys, for your assistance and friendly attitude to a total newbie.

@easy rider a link that might be useful
