Well, looks like I still got an error here.
"Unfortunately, Streetpilot has stopped" keeps appearing. I used the apk that Ellinas uploaded. Already put the Garmin folder in mnt/Sdcard before installing the apk. Tried to check in the application info, looks like the apps still doesn't recognized the data folder. Here's the screenshot

Try to get logcat extreme app installed. Run it, then run Streetpilot, then go back to logcat extreme and save the log. Upload it for us to look at. Maybe it will show at what point Streetpilot crashes.
Doesn't work on 4.2. Needs to use root on Jelly Bean. From Android 4.1 onwards ANY logcat app needs root access in order to show logs .
