catymag i read about installing multiple maps and units and directories, but one thing i couldnt understand. I hope you could clarify this ;

- I m using Garmin 3790T model device. And i have a 8GB memory card that i would like to install several mapsets in it. Now in your posts, the new devices such as 3790 accepts anyname.img maps on SD card under MAP folder. But my question is what about 3d maps and JCV files?

- For example if i want to have the whole Europe mapset with 3D maps and JCV etc and whole North America mapset with its 3d maps and JCV and also middle east and north africa with the 3d maps and JCV files, how do i place the files?
- Do i simply place everything unders MAPS folder under SD? or do i have to rename the 3d and JCV files and put it in another location? Are there any restrictions on 3d map files and JCV files that we can have on the SD card?

I would appreciate your assistance, thanks.
