Has anyone studied this feature in the Garmin at all?
I'm trying to find out if there's third-party software somewhere to create your own tour guide files. This would be a boon for MINI outings. A tour organizer could dictate commentary and instructions and save them as MP3s, put them on however many SD cards, create the TourGuide route in their *.gpx format with all the key path points defined, and supply them to the group leader, tail, and others. When you motor close to a proximity point, the associated MP3 plays.
I don't know if that would override the standard voice prompts or not. "In point two miles..."
Hmmm... just found something...
...and edit again...
