I will apologise in advance for my stupidity, but I am new to all this tech stuff. So far I have managed to download the 9 parts of the file and extract them into one file. This is called "GMAPSUPP" and it is just over 1 meg in size. I then copied this to my SD card inside a folder called "Garmin". My chartplotter on my boat can't unlock it. I tried it with both the lock on and off on my SD card and still no good. I noticed that when the SD card is unlocked I end up with another file on my card called "GarminDevice" which is 2kb in size. I also found another small 1kb file called "GMAPSUPP.UNL" which I thought might be the unlock key so I put that on my SD card, inside the "Garmin" folder, but still no luck. When my chartplotter first boots up I can read on the bottom of the screen that it has picked up the chart because it says something like "Brisbane to Geraldton", but then I get a big screen saying "Can't unlock chart". I bought this chartplotter in the USA so it is preloaded with the USA map, which is useless to me here in Oz, so if someone can help me I would be greatly indebted.
Many thanks in anticipation.
