When upgrading the Media Nav on my 2019 Clio IV it told me that I should not turn off the engine while upgrading. It turned out that the upgrade took a pretty long time. I was essentially braking Danish law to upgrade, as it is not allowed to keep your car in idle for more than 3 minutes. Besides that, it is really bad for the environment to sit around with a car in idle for 30+ minutes while upgrading the entertainment system.
I know that the reason you want us to keep the engine on is so that the Media Nav does not turn off during the upgrade, but maybe there could be a more clever way to design this? For instance that if you are running an upgrade, it will not turn off.
What is Renaults thoughts about this?
There really is no better solution to doing it. You said it yourself, to make sure it doesn’t turn off. If it would turn off during an update you risk “bricking” the system making it almost as useful as a brick.
