Point taken. A lot of the earlier info is quite misleading [wrong or simply out of date]. When i get time i'll do a summary for current situation for the common devices' usage of maps on SD/microSD and put a link in Post #1.

When threads get as long as this one, i find it helpful to read the first page or so, skip to the last page and then work forwards & backwards until you get the relevant info [a bit like building a bridge, but hopefully you can stop before you meet in the middle, lol!]. Thanks for your constructive comment.
