Nice work! thanks so much for the effort you are putting into this!!! I got it loaded up and GPS and Music working. Seems to boot up very fast. I followed the steps, the question I have is each time I turn the car on after turning it off to go somewhere, I have to follow the steps as on the first page? Seems I do or it won't work with the audio?
A few things I noticed.
1. One of the biggest issues is in core player when you select the songs to play after pressing play, brings up the white screen with OK in the bottom right corner. Every time I push that it brings up the small input panel for Wince. This made it impossible to select ok and play the songs. Only 1 was I able get OK to work and it played the songs fine. I think would be better to move away from the corners like the buttons are and bring them in more to the middle of the screen?
2. GPS worked fine no issue, however master volume on GPS software set low, this caused audio music to be low until I turned master volume up all the way on the gps software.
3. In core player when you select the media button and albums I never saw the album art for the 2 albums I have, however I was able to press play, the one time I got the music to work (see #1 above) I did have album art on the screen then just fine. I checked the edited location it seems correct, I'm using jpg, your using png difference?
