Can Striker 4Plus quickdraw data be transferred to a Striker 7?

[vtgarmin]

I've been using a Striker4Plus for a couple years and have lots of local contours plotted. I'm thinking of buying a Striker 7sv Plus but would only do that if I could transfer the data I already have to the new sounder.

Garmin online and manuals say you can connect the blue and brown wires (alternating colors) amongst the Striker family to transfer data "like waypoints" between units. But it doesn't say what other data besides waypoints can be transferred.

I don't care about waypoints. But I don't want to drop $500 on a new sounder just to find out I can't move my quickdraw contour data over.

Does anyone know what data can be transferred by wire from the 4Plus model?

Thanks!

Might call Garmin but i dont believe you can since they dont have a card slot.....i THINK only way would be to up load files to the QuickDraw website where it would be public and then download to the new unit via AC app.
