Apple carplay and Google play and Wiki camps

Short answer, no, check the FAQs. Long answer check this forum, there is a third party device that allows this.

I assume you mean Android Auto rather than Google Play. If so you can mirror your device onto the cars display once connected via USB. Google Android Auto mirrorlink. Can't help with Apple stuff or the send directions part of your question.

The ExplorOz Traveller app works on all ANDROID headunits. ie. headunits that have the Android operating system. This is because these headunits will give access to the Google Playstore which is how the app needs to be purchased/downloaded.

The Apple CarPlay system is not compatible with the ExplorOz Traveller app so if you only have the Travleler app on your iPhone and have a non-Android operating system headunit then no you cannot use the app on the headunit from your phone via CarPlay unless you invest is a gadget called an Android AI box adapter - these supply an Android operating system in a USB plug in adapter that you can connect to your headunit. It then allows the headunit to run the Android OS. These are available on the internet and from our preliminary research as an IT business, our recommendation to anyone wanting to get one of these at the moment would be to look at the CarLinkKit brands of AI adapters CarLinkKit TBox Android 12 AI Box
This page has good info, and a good video. The one I've linked to shows a cost $249. Think that is US$?

EDIT (forgot to reply to the second part of your question before hitting submit)....
The ExplorOz Traveller app doens't need to send directions to Google for you to create turn by turn guidance instructions. Simply use the built in navigator features. If you haven't figured out how to use that feature, just look it up in the User Manual - specifically see Trip Planning (from the index page you can jump to this, which starts on Page 24).
