I plan on getting a gps bundle soon, in addition to using the pda for gps I would also like to use it as a touchscreen mp3 player. I was wondering if anyone has had any experience with this. I would like to have the mp3 running in the background while the tomtom or other gps software is running. I have a cassette player so I am going to use the line out to cassette adapter. If anyone knows any good mp3 players that can be good for touchscreen please let me know.
Thanks
