But how do I install an land map on garmin 620 and at same time have my bluechart map also?
I cant figure out how to put both land ans sea map on my sdhc card, the garmin dosent find the cards if they are renamed to any thing as GMAPSUPP.IMG.
And i cant have 2 files with the same name in the same folder.
I have an 4 Gb card with an bluechart map on, works nice.
I have the bluechart map on the sd card like this x/GARMIN/GMAPSUPP.IMG
It works fine.
If i put the landmap on the sd card like this x/GARMIN/GMAPSUPP.IMG it works fine also, so both maps works fine seperatly.
So how do i get both maps on the same sd card?
Now i have found out that i have to use GMap tool and join the 2 files into one.
But it dosent work quite well
Not all details of both maps will show up.
