Does anyone know of a download site that has programs to alter the splash screen on Magellan products? I used to have a program 2 years & 2 computers ago that would allow one to put contact info into GPSr in the event that it was lost. Tried to Google for results to no avail. Also interested in other Magellan hacks. I'm working with a Sportrak Pro, for what its worth... Thank-you!
