Posting to say thanks and to let everyone know that Streetpilot is working wonderfully on a Samsung I717 Note running 4.1.2. I used the files and install instructions from the beginning of post 1. I had to edit libgarminos.so back to the "before" for the battery icon and also to use the maps on the external sd card. I find the resolution is perfect for the 1280 x 800 display on my phone. The app takes 4 seconds to boot up to the license agreement screen.
I noticed there is an error in the Garmin.rar upload. The basemap file is gmapbmap .img. (Notice the space between p and . which is not correct nor allowed for android)
Edit: how do you get the dashboards to work? It is not showing up in Map and Vehicle menu.
