hi all,
I am new to the garmin range and have just downloaded the bluechart g2 vision for the east coast of australia. This is to be put onto a friends garmin marine gps/sonar (gps map 750s). I downloaded 3 parts of it and they are a .rar (VCP022r.rar) file. Just wondering what I need to do next? Do i just put these 3 files onto a blank sd card and put it in the unit or do I have to change the format of the file?? I haven't tried anything yet because my friend lives a fair distance away from me and I need to know what to do with this program before I make the trip around to his place. Any information would be greatly appreciated.

cheers from john boon

I don't want to sound rude here but if you don't know how to handle a rar file than I strongly recommend to do some reading in the tutorials first.
You need Winrar, the Jetmouse keygen and the knowledge from the tutorials.

well i am extremely new to all this stuff so some patence and understanding would be great

download winrar
put rar files in a folder,click on part 1 and extract it
run on img ,unlocker alternative by pietu to unlock it , rename the img as gmapsupp.img, copy it in a Garmin folder on your sd- insert the sd in your plotter or you can see it with Homeport on your pc

Just in case make a backup of all files first - using the Windows Explorer ;)
