Hi,
Well I feel a little unsure asking this with 3 of my 4 favourite experts on the thread all I need to complete the fearsome 4 would be the little man with the extended digit.

This question maybe because I have misunderstood but here goes, From Catymags excellent description and Tom & Midnight Blues, I got the idea that I could perhaps on an SD card in the Garmin directory put sub directories of JVC ASR MAP to Put 3d in and all would work, but no luck also I should point out I am using a 3790 so as far as Caty's assertion to put all the above in Garmin directory they will NOT work they do a fantastic job in the .System folder in their correct subs and the 3d1, but not anywhere else.
So is there any way to put JCV ASR & 3D on an SD card with their appropriate map to avoid filling up the .System folder and also then be able to use 3d for say a third map.
I have read every thread and gotten the impression it is doable but cannot seem to be able to get anything other than the map to work.
This probably me or it may be something to do with the 3790.

Hopefully there is a solution.

Many thanks
