Good Sam Trip Planner to Rand McNally RV-70 Transfer ?

I looked in my Rand McNally manual and did not find what I was looking for. I remember having to save a trip to a different file type, then load it into the SD card.
I will continue to look.

I found this in Trip maker help:
Once you've planned your trip, you can email or print the trip itinerary or you can export to any Rand McNally GPS device. Click on the Trip Manager tab and follow the on-screen instructions.

I have the RV70 and according to Rand McNally this model does NOT support the transfer. I was told this by both Rand and one of their reps at a show.

Page 8 of manual:
2 TripMaker® Use the online planning tool to plan a trip with multiple via points and transfer it to the navigation app as a multi-stop trip. (See help available online.

Sounds like you may have to do trip planning by wireless then transfer to the navigation.
