Route imported from google maps to Basecamp will not hold defined route, straight line from A to B only

Hi all,

I've seen this mentioned a lot on the forum however most threads are years old and any new posters are asked to start a new thread so here I am.

I have a trip planned for the end of this month so have been hammering away on google maps trying to sort out the most scenic route that I have time to do. I am heading from N.Ireland to County Kerry in Ireland, one of the most picturesque places on earth in my humble opinion. I can plan the route, convert it and import it into basecamp (Latest version) however everytime I try to convert it to a route I only get a straight line?

I have seen a few posts saying to try direct track instead of motorcycle, this seems to work on basecamp but will not load onto my device.

I have a few days to get this all sorted, any ideas or alternatives to basecamp that I could use? 

Thanks in advance.
