Hello Jengroro 3,
For the ray :
You can use the streetpilot V.1.49 (gives in post 3, like Cathymag said) or V2.14tw (you can find by searching on Google).
The difference is just to don't have the other application SP Language. Take the files of your language that you need and put manually in the "\data\data\com.garmin.android.apps.gmobilext\Text".
Language file are like this : "fr_FR.glx" + "fr_FR_PRX.glx" + "fr_FR_TRF.glx".
Then download the Libgarminos of CathyMag : 26SP_201_Sony+Ericsson+Xperia+neo_ext_card_by_rf71 1.rar (gived in this page)
And overright this file with the file Inside "\data\data\com.garmin.android.apps.gmobilext\Lib" (like explain in post 3).
After it run StreetPilot, then after to be in Menu, close application and go in "data/data/com.garmin.android.apps.gmobilext/system/SQLite/system.db" give authorisations like this to this file : « r-xr-xr-x ».
After it, everythings is finish and you don't need to do again. Just use app like you want.
And of course, you can use ".img" with this software :
Put ".img" inside Garmin/Map (in you SD Card), you can change the name of file, it's no problem (ex: Moon.img
Just put the Base map in the folder of SD : "\Garmin\.System" the name of base map should be "GMapBMap.img".
You can find world free map in this website :
(it's free but it's really nice).
