Unless I am misreading it, we cannot add HERE to this application. Maybe someone more adequate in legal aspects can confirm/deny.

It looks like you cannot display search results from HERE on a map , if its not HERE tiles. This is based on https://legal.here.com/en-gb/terms/a...ble-use-policy , Layering and Modifications; https://developer.here.com/faqs, Licensing & Terms, Q7 [but Q9]

I think its illegal to use HERE routes in navigation apps. See https://legal.here.com/en-gb/terms/a...ble-use-policy, Application Restrictions , paragraph with "Route guidance applications"

Which means that I can drop plans on adding HERE as a service. Which is pity, they could have been great option for online service.
