Finally got this to work on my Samsung Galaxy S5 running AOSP (Android 7). I am using the CN Europe 2019.20 NT map but cannot find which JCV to use with it. I tried using D2504260A, which is the file that is running fine on my old Nuvi, but it is not showing any junctions on Street Pilot. Can anybody please let me know which is the right JCV file to use with this map
