TOPIC:

5 weeks of new 2019 Black Edition. Only minor gripe is that it’s random what the head unit plays on start-up USB, FM radio or Digital Radio.

As you probably already know, whatever you were listening to when you switched off, i.e. radio or USB, should automatically play on start up. If not, report it.

As above really. It's just another one of those weird ones that the Renault techs never seem able to resolve. Whip it back in and see if they can do a full reset, (not the one we can do as drivers). Mine doesn't differ in what it plays, just when it plays it. I can travel a good 1/2 mile some days before it blasts out, most days it's as it should be, instant.

Very often, I switch off after listening to music on USB only to find the radio when I next start up, and vice versa.
Irritating, but not a deal breaker.
