Apple/Google Maps, CarPlay, Pre-Planned Routes

[mattyn1]

Hi All

I have a series of KML Files downloaded from a website that show specific routes abroad - that I intend to follow on a forthcoming road trip.

I am a bit stuck on how to then transfer them to be able to be used ideally in Apple Maps or alternatively on Google Maps. Again, ideally on Apple CAr Play, but should that not be feasible, then on my iphone.

I have downloaded the maps from here: https://www.drivingroute66.com/route-66-maps/ (and they are the KML files) and have downloaded MyRouteApp - but would like something a bit cheaper - seeing £150 for life time membership is a bit extreme for me.

Also have seen this from previous threads - https://www.lifewire.com/make-custom-route-on-goog... which I can get into tonight but looking to the masses here for any other simplistic ideas.

Like I said, prefer Apple Maps - and assume they will work the same as downloaded maps normally do - considering some of the areas we are going will be lacking a mobile signal!

Thanks everyone.
