Interesting that he's been able to do that. You'd have surely tried asking him about it on the other forum so i suppose he doesn't want to part with his secret. Unfortunately, many ppl don't like to fully share information, preferring to only show the results, what they can do but not disclose the actual mechanism ..... or perhaps like many of the former Garmin coding experts here he's simply been scared off by Garmin's actions against our other prominent former forum members.
