Anyone transfer trip from Good Sam (Rand McNally) to Garmin?

 

I use a trip planner from Good Sam that lets you download your trip to a Rand MacNally GPS; My question is can you 'convert' somehow so I can download from Good Sam trip planner to Garmin? I'm looking to buy a Garmin 760 for the RV.

Bought a new Magellan 9490 for our RV-it wouldn't pick up the satellite on our test drive so I sent it back for a refund. Could not transfer address book from 9145 to 9490 (different OS, I'm told); well, I've had it with Magellan!

Thanks
Bill
