MG4 Trophy not reading speed limits reliably

[NickL]

I have an 8 year old Qashqai and it reads the speed limits reasonably reliably. I think it defaults to the inbuilt sat nav if it cannot see a speed sign nearby.
My MG4 Trophy struggles to reliably read the speed signs. For example, on a motorway with a 70mph limit it may sometimes show 40 or 60 mph, other times nothing.
Is there a way to get the MG4 to also read speed limits from the in-built satnav?

Do others have a similar problem?

Yes, the speed limit recognition is awful!
Hidden away in the Trophy satnav menu is an option to show the speed limit on the satnav screen. I have found this to be much more reliable than the speed limit display in the driver’s binnacle.

I can also attest to the fact the speed sign recognition is crap. But its easy to ignore so i do

Yes, I turn it off if I remember to.

Just out of interest as I've seen a few comments about the speed recognition, when you see the 40's or 60's being shown are you going past junctions, off ramps adjacent roads etc?

This seems to have been a common issue across various manufacturers whilst they are getting their systems dialled in as the cars start to get some real world miles under their belts

Saw exactly this happen on Sunday evening, but I have been surprised at how good the system is at reading speed limit signs, I expected it to be very hit and miss but it got every single one on my trip including one of an off slip road.

Yes. It's absolutely useless and it's a shame it can't be turned off permanently. Comes on again every time, like the infamous LKA.

I bought my MG4 Trophy in October 2023, the speed traffic limit Reader is an awful liar.

What infotainment software version are you on? R46 brought a lot of much needed fixes including the bluetooth connection and speed sign accuracy.

 

[mg4mc]

Does it fix the lack of knowledge of what the national speed limits are? Mine nearly always shows 60 on motorways and dual carriageways.

 

[NickL]

It is only as good as the information it has.

Even my dealer admitted (in a whatsapp response) speed sign recognition is very poor.
It almost makes me think you are driving something else than an MG4.

The option of using satnav is no alternative:
1.Speed is not shown on the driver dash,
2.it is plain wrong as the maps are outdated and
3. because it uses the wrong max speeds on highways.

I just keep my eyes open
