Speed Recognition

[Dirk]

I have a 2025 HS PHEV trophy, less than 1 week old. Generally happy except for the awful speed recognition and subsequent "bongs". Outside of 30 and 5o zones, the system is ALWAYS wrong, for example on the M4 from Swindon to Bristol it claimed the limit was 40! I havent noticed it accurately notify the national limit at all, ever! Has anyone else got this problem before I contact the dealer?

Try following a continental bus on the motorway and watch it translate the 100kph sticker on the back of the bus to 100mph on your dash.
My Insignia did the same in the middle of Bristol

Strangely it started to work again yesterday, national limits correctly identified as 60 or 70 - perhaps some OTA update?

@Dirk - For what it's worth, my car's infotainment was upgraded from R46 to R62 last week. Since then (because of roadworks) I've gone past a 'national speed limit' sign (white with black cross) 4 times (I normally don't go past one). Each time I've checked to see what my car says. Every time it instantly changes the display screen from a red 30 circle to a red 60 circle (correct) immediately after crossing the boundary.

From my memory, I think that in the past (R46) it used to show the white circle (with black line) symbol (instead of red 60 circle), but that could be a false memory in my aging head!

Naturally the system relies on the camera, so if it's cold/frosty, or rainy, or foggy, then the camera may not be working properly. That might explain it intermittently failing.

Oh, and I may be wrong but I don't think we ever get any OTA updates. I think only the garage can perform them, so (in theory) your intermittent problem is not explained by infotainment software updates.

My car tells me the limit is 90mph in a 30 zone.

Another time it claimed the limit was 115mph. Very strange.

I had a leaf get stuck on my front camera when I got home and noticed it I removed it no problems since.
On another point I had a drumming sound looked every where then found it was the sun visor which I had moved to my side window to block out the setting sun and had not made sure it was back in its correct position.
