The reason why we have so many different versions is because the path to Garmin folder is hard coded in the executable .so file. This app will only access that path for maps, languages, voices, ex... What version you pick depends on how your device Storage is setup. So you have to check that with some file manager. Then the other question is are you rooted or not. Some not rooted devices can only access access the /sdcard/Android /data... Some people prefer to install on internal storage so they pick sdcard0 version. Others like external so they pick sdcard1 or extSdCard. Now what ever version you pick that's where the extra files should be places. Other folders are not used. Not knowing exactly what path version you installed, I can't say what folder is actually used. You can rename the folder and start Streetpilot. If this folder was the one used, you won't be able to get passed the language setting. It will also make a dummy Garmin folder which you will need to delete to rename back. If Streetpilot actually started normally with folder renamed then you can delete it because it uses the other one. Hopefully I cleared something up and not confused you more.
