Strange blackout

[the2ems]

Just had a weird occurrence. I was coming to the end of a 30 mile round trip, when suddenly, without warning, the touch screen and dash/heads up display, all went off. It didn’t affect the driving. It all booted up again after a few seconds. But not instant pop, and all back on. It was a proper boot up. Possibly slower than when I start the car from cold. Everything seems fine now. Has this happened to anyone else?

Our 2017 C4 Picasso has done that a few times, no idea why!

It happened to me only yesterday in the X7. I had just started the engine and was manoeuvring out of a car park when the radio suddenly went silent and I realised the RT6 unit had rebooted. It's been a while (years?) since this last happened and I just accept it.

It has happened on the SMEG+ unit in our 308 as well although not for a few years.

And you're right, it seemed to take longer than the normal boot-up from cold!

It’s happened again.

Get it back to the dealer - it very likely needs a software update / check. If the Head Unit is overheating it will generally reduce the volume of any audio in the first place, but if this is not the cause, then it's a problem. There should be a log stored in the unit that they will be able to retrieve at the dealership.

It happened to me 3 times since i got my car. My dealer told me that's probably caused by software updates, since my software was up to date when my car was in the garage.
However, my software version is the same since day 1, even after several OTA updates.
