Is there a way to disable the screen timeout when the engine is off? I'm at a drive in cinema listening through FM and the screen turns off after 5 or 10 mins.
Not that I know of. Map updates (via USB) can take a while and have to be done with the engine running to prevent screen shutdown. So they're done on a reasonably long journey.
All I can suggest is a radio app on your phone.
Good luck!
You might - which audio system do you have? Those watts don't come cheap! And it's not just the battery capacity - you need enough amps to turn the engine over.
After an hour and half I had to turn the engine on for 5mins because the screen wouldnt turn on at all but there was no issues, started instantly, and then again was fine after the film finished. I've got the base 380w system but even so the movie sounded fantastic. Saw Joker, very enjoyable experience, just wish I could have reclined the seats further!
