We've lost the time display, both the big one when the infotainment system is off and the time on the title bar when it's on (next to the OAT).

A message saying "No time information" appears instead of the big clock.

Restarting the car hasn't brought it back.

Anyone else experienced this?

 

[Paul M]

have you enabled time sync off DAB or GPS?

 

[Nickel]

GPS, it was set on, and I tried DAB, but no change. Nothing happens when I select Manual.

We noticed it when setting off after a charging session but I've no idea when it actually happened.

 

[Nickel]

Well, having been parked up overnight, time resumed it's normal passage when the car was powered up this morning. All now looks normal.

So goodness knows what happened there.

 

[Noraf142]

Interesting. So no clue as to what have happened then.

 

[Nickel]

No idea.

We had the car satnav on, and my wife had been checking the time, so is sure the clock was working shortly before we stopped

We were 20-25 minutes at an Instavolt that we've used before, and we can't think of anything unusual that happened. Just no time display when we powered back up. The satnav continued to work fine.

See how we go, I suppose.

Yeah, the MG seems to have severals Gremlins in the works. Others have reported odd things happening sporadically. Mine doesn't always quite clear the infotainment screen when I go into reverse. I can still see opaque versions of the radio, sat nav and Android Auto/CarPlay selectors.

I am not sure where you are based but possibly this is the reason ...

Jamming trial impacting GNSS (GPS): 17 – 28 August, Wales and SW England

Interesting.

The first hour and a half of our journey was inside that circle, but we were outside it since a few miles after our previous stop at Michaelwood. We were doing a splash'n'dasj in Evesham when the problem occurred, well outside.

But the GPS itself behaved fine all through.

Would they be jamming at ground level? It'd cause chaos with no obvious route to notify users, unlike pilots who have NOTAMs etc.

Curious though.

 

[Nickel]

I'll revise that. I went the wrong way from nautical miles to statute miles. We were on the circle at the problem time.

 

[RicM]

Nickel, it appears related to precision timing ...

'The activity may affect GNSS navigation and precision timing devices'

May affect GPS for aircraft at altitude probably in which case the pilots would have the NOTAMS and will have received a RAIM report to determine GPS reliability in flight ...

As for ground level, it is quite likely that the precision timing element of GPS could be affected without affecting ground GPS navigation itself such as that used in cars. I understand that the jamming is to test the timing of the satellite to ground reception to calibrate it (correct me if I am wrong GPS experts!).
