Hey.. thanks for your reply.

I did make the M50gpsapp executable. Here's what a ls looks like on the player:
empeg:/etc/preinit.d# ls -la
total 3
drwxrwxr-x 2 0 0 1024 Jul 1 2001 .
drwxr-xr-x 4 0 0 1024 Jul 1 2001 ..
-rwxr-xr-x 1 0 0 110 Jul 1 2001 M50gpsapp

If you can think of anything else I may have missed, please let me know again!

Thanks,

Brian
