Roy,
I bought the Navionics PC app and I have been able to transfer waypoints from my PC to my HB and vice versa using a clean SD chip. All of a sudden I can't get the data to transfer. I would have thought that when you saved the WPs and sent to your friend it would have updated his unit when he started it up. That is how mine worked until it just quit working for me.
I posted this as a question on this forum but out of over a 100 views, no one had a suggestion.
Hope someone can clue us in.
