Have not tried "send to connected device" Will do so.

However, are there any limits re number of routes or other settings that affect whether sync sends a new (yes I saved it first) route to the card?

Cheers

Both synced OK, but initially when I put the new route in and I synced it and there was no route, however when I clicked 'send new route to connected device' under 'go flying' it transferred it OK.

There was no problem with SD though, I just hadn't saved the new route. as soon as I did  it transferred OK on both computers.
