u/My-Internet-Persona

I am preparing to buy a new Dacia (my previous car was a Dacia, too), and I am undecided about whether to buy the navigation software or not.

The car already comes with the MediaNav display, so in principle I can just plug my phone into it and use whatever I use on my phone (Google Maps, Mapy, Waze etc.).

Under these circumstances, is there any good reason why I would pay for Here Navigation? Is it superior in any way to the phone-based alternatives (some of which are also free)? In general, it is said that "paid" cannot beat "free"; is this true in my situation, too?

EDIT: I forgot to add that I use Android - not that it matters much.

Until quite recently, I have read that Firefox on iOS was just a wrapper around WebKit. On the other hand, I understand that there are some recent EU regulations that force Apple to open up its operating system to competitors, for the EU users.

I am a die-hard EU Firefox user (since Netscape times!), and buying an Apple phone depends essentially on having a real Firefox on it (complete with Gecko, that is, as opposed to just a skin on top of WebKit).

Hence the question: has Firefox on iOS switched its engine from WebKit to Gecko, for EU users, or is it still a thin layer on top of the Apple libraries (web engine, JS virtual machine etc.)?
