I have a Navsure 420i, with original map sd card... but my map software is missing/corrupt.
I tried using the naviextra software toolbox to recover things but got to the point they wanted 80euro's - much more than the units worth currently!!

I can have my card recognised by the navitoolbox - so that at least means i only need to find correct maps and add them to my sd card in the relevant folder - my issue is..... I have no idea which is the correct folder to put the maps in or in which format the maps should be added... I have a set of Igo8 maps for the uk.. in *.rar / *.fbl / *.fda / *.fpa / *.fsp & *.poi .... I read somewhere that as the Navsure uses Igo8 that these files should be compatible....
My issue is on the sd card I only have the following folders :
Addons
Backup
Navigation
System Volume information
device.nng

each has its relevant files included, except any actual maps (as far as I can tell)...
navigation/data/ui_igo8
seems to be the folder I would expect to find the maps...

Anyone any ideas>??????

Much appreciated
