2. Tap on the arrow within the blue circle
3. Tap on share location, choose email
4. Send it to yourself.
5. On the email, there should be a link and a vcard. Both of them include coordinate information. However to get the actual coordinates you'll need to copy the link in the email and paste it into, e.g. Notes, to then select just the coordinates.
