Can someone explain how to import or add POI's to Mobile PC? Garmin Support tells me that one can add a personal POI or import POI's. I believe the POI's supplied with the latest version of Mobile PC is not as current as it might be. The ones I have with iGO8 R3 is much better. Can I use those? I do not understand Garmin's file structure and have no idea where maps and POI's are located.
