Lowrance/Navionics

[Blue_Heron]

My older GPS is a Garmin with Bluechart cartography. I really like being able to manage routes, tracks, and waypoints from my computer, so the Bluechart filled the bill. For the 25 Seafari, I needed a new bottom machine and Lowrance just seems to have better fishfinder technology than Garmin.

I ended up buying the Lowrance Elite 5 DSI Gold which is a combo unit that comes with Navionics Gold Cartography. I wasn't really looking for a GPS, but it wasn't that much more than the straight fishfinder unit. I'm impressed with the map coverage. It's got charts for every place from Cuba and the Bahamas to the freakin Northwest Passage. What it doesn't come with is software for managing waypoints, routes, and tracks.

Can anyone recommend a software package that does that and is compatible with Lowrance and Navionics Gold?
