Hi I am new here .
I bought a g2 vision card off ebay east coast map of Australia.
I put it in my new garmin 7410xsv plotter/sounder and nothing works .
I have looked around on the net but struggling to find solution if there is one .
I opened up the sd card and i have a folder named Garmin
in that folder i have 4 folders
GarminDevice xml doc 2kb
gmapsupp
gmapsupp.unl
GPDATE.GCD
Any help or tips to get this running would be greatly appreciated .
Many thanks Greg
