Map Changer for Nextgen on Android 13 OS

Me too
has_secondary_root=1
android_secondary_root_path="/storage/40FB-A3B3/addons"

works fine as I said in my post #4 with skin Arimi.

has_secondary_root=1; is well-known and standard, every iGO user should master it by now 😉

is then irrelevant (but can be left unchanged) if all files are in the data folder - which should actually no longer be a problem with today's devices +>64 GB of memory

Sure, but Pongo makes a big cauldron with a Big Map Soup.
Arimi's Map changer method is much more rational and clean.
We just have to find the possibility to access the com.gja.nav.utility Folder or program the access to unprotected standard folders on SD with the possibility of having separate folders for each Map Provider.

gja is old utility, not intended for new editions
if you think that someone will modify it, you are a great optimist

Fixed, at the moment it's the only solution for me.
On the path android_secondary_root_path="/storage/40FB-A3B3/addons" (therefore in the Addons Folder) create two Folders: Content_TT and Content_Here. When TomTom is needed, rename Content_TT to Content ; When you need HERE, rename Content to Content_TT and Content_Here to Content. All this of course before starting iGo. It's longer said than done.

So do it first, (and better), to do it like this:

create two folders instead of the "addons" one, MappeTT and MappeHere containing the folders that are in addons, (content/building, map, poi, etc.), and containing the files of the related maps.

in the sys you create a path for the two maps:

android_secondary_root_path="/storage/40FB-A3B3/MappeTT"
;android_secondary_root_path="/storage/40FB-A3B3/MappeHere"

by deleting and adding only the semicolon with the File Manager you can use the maps you like.

Thanks Birbante, this is another trick I hadn't thought of.:good2:
Grazie Birbante, questa è un'altra furbata a cui non avevo pensato.
