The head unit in my BMW turns itself off and back on again every now and then. It can go weeks without an issue, and then other times it can swtich itself off several times in a day.

I've been led to believe that a software update by BMW would be the best possible option. But they are saying there is always a chance that the Unit could completely malfunction when doing the update.

Does anyone have any other suggestions?

I've tried holding the on/off button on the unit (that was a YouTube recommendation), and we tried doing an update from the BMW website, but that's not a full update apparently.

I really don't want it to break completely :(

And couldn't afford the 3k to get a replacement put in

Thanks
