Hi all
I am a newbie here so firstly "HELLO"
I do not have any Garmin Equipment, all i want to do is use my laptop to view marine charts.
I have downloaded the 10 rar files and extracted them which gives me a file called gmapsupp.img
I downloaded Homeport. I have 'Global Map' How do i manage to use the img file with Homeport?

I tried import, but that doesn't work as i think it is looking for a different filename.

Can anyone please help me.
Many thanks.
BTW I used to use Mapsource BlueChart which was easy as all i had to do was install to my laptop and it worked 1st time but that was a few years ago.

Cheers
