I am looking for some software for navigation on laptops.
It should use Garmin maps and taking the GPS information from an attached Garmin GPSr.
I would like to use BlueChart G2 Vision maps. The former nRoute has big problems with G2 Vision charts and the old MapSource 6.5 cannot handle them at all. MobilePC 5.00.70 does not have any marine charts handling abilities either.
I think Garmin has stopped the development of these software products for marketing reasons. They just want to sell their GPS units.
I would like to use this software as back up system on my navigation table inside and my Oregon outside in the cockpit of my boat.
Every advice is welcome!
