I have an etrex Vista HCx that I would like to install Topo Aus & NZ V3 into (actually a 4Gb micro SDHC card). I have Mapsource, Basecamp and Mapinstall all installed on my computer. I have downloaded the GMAPSUPP.IMG file and I have the Jet Mouse unlocker. My problem is that I do not know where to install the *.IMG file so that any of the above programs can see it so that I can use Jet Mouse to unlock it and then the relevant program to send the unlocked file to the Micro SDHC card.
I hope the above is clear...basically what I want is to have Topo Aus & NZ V3 on an SD card that will work in my etrex. Can someone please help?
Thanks and regards.
