Plugged it in this morning and its gone daft,not working properly;it's only a week old.

 

I suspect it needs rebooting? How do I do this please? Can it be done while plugged in or best not plugged in?

 

Also does it matter if it's removed during the countdown shut off thing that it does?

Plug it in and give it a long recharge. The battery is useless when not on a live mount. If on standby it will quickly discharge. All sorts of problems occur when battery low.

Brand new unit or secondhand?

It's a brand new unit which came with the car 9 days ago.

 

It's mysteriously righted itself now on its own

That's good then, just a tip to keep in mind, but it might become unusable after a year and a bit, changing the battery solves this problem it seems
