Just a few notes from my side:
- the proper folder name for the Auto Speech Recognition files is ASR, not gmapsupp.ASR
- the proper folder name fot the Junction View files is JCV, not gmapsupp.JCV
- the proper name for the 3D buildings and landmarks file is gmap3d.img, not gmapsupp3d.img
- You can check the proper function of the Junction View feature by simulating a route along which Junction Views will be encountered
