I don't use OsmAnd for car navigation either.
I have used Here as well as it is very good and fast, be it very limited in functionality compared to OsmAnd.
However, your comment "The blog is down, no map updates due to "improvements", it was nice while it lasted." is of course not a correct one.
First of all: the blog is not down. It is still there at
osmand.net.
Secondly: There is one month no update and you stop using OsmAnd?
Here updates every 3 months on average. If it is for the map updates you should not switch to Here but stick to OsmAnd (or switch to Navigator with monthly updates or switch to the other Open Source navigator Maps.me with irregular maps updates).
