Loading up my Garmin GPS

Hey guys and thanks for any help in advance.

I am new to all this and really have only had a couple of prospecting trips back in the 80's with little luck. I thought i'd join this
group to build on my knowledge and gear-up for a trip early next year (maybe April when it's cooler)

I have done all the playing around in Geo-view and find it is great for researching the location though i now want to be able
to load up all the tenements and metadata onto my Garmin GPS.

Can one of you kind ppl give me the link to download these files and advise what format i need them to get them on my garmin.

Also can i only load them to my GPS using the Geomap program which i know nothing about ? or even where to get it ?

Looking forward to your replies and appreciate your help.

regards Alex

Are you guys using GDA1994 or GDA2020
I assume all Garmins\s handle any grid ?
