I've successfully installed SP v2.16 using StreetPilot_216_no_root_sdcard.apk copied the Garmin Folder on Phone Memory on my friends SGS 2. Works great! battery and Satellite Signals and Volume (though need to adjust volume every time SP is open) with 4.1.2 I9100DXLSD firmware Non Rooted. But on my SGS3 with 4.1.2 I9300XXEMB6 the battery icon works fine except the satellite signals still in red!

I guess firmware version gives different results..
