Hi tom1808,
Sorry. A slight change of scope. At first, I thought only encrypted POI files could be placed in the Where-To menu. Now that I know it is not required, I decided to make the POI Loader equivalent and provide this ability. Loading WAV and MP3 are much easier than I thought. They are next in line. As for proximity and speed alert, I just need an evening more to finalize it. I already got 99% of it. There is just one byte that is bugging me.
I guess crypted poi files will be for a next challenge. So far, I just decoded a few bytes by hand. I am far away from decrypting the entire file automatically.
