2020 Jaguar XE P250S

When I first bought this car, the navigation would display the speed limit. For some reason it has stopped doing this.

Does anyone know how to get it going again? I've done everything I can think of and read the owners manual looking for the answer.

I understand that the car does have a feature that uses a camera to read speed limit signs and then display the speed limit in between the speedometer and Odometer, but it should also display in the navigation.

 

That's a good question, I bought my car used, and it says it should display the speed, even enabling that functionality in the nav settings it never has / won't display the road speed limit. Ill be interested in the insights you get on this.

 

My 2017 XE displayed the speed limit in the Nav without issue. When I drove this 2020 XE off the lot, I'm pretty sure the speed limit was displayed. I don't know why it went away.

I'm taking this car to the dealership on December 11th for an unrelated issue. I'll have them solve this nav problem as well.

 

From everything i know on the redesign, its shows in HUD and Cluster and not in navi screen itself



TRAFFIC SIGN RECOGNITION (TSR)

ITEM DESCRIPTION 1 Instrument Cluster (IC) 2 Head Up Display (HUD)Traffic Sign Recognition (TSR) captures image data of the road scene. The Image Processing Module (IPMA), within the camera, infers speed limits implied and read from the scene.

The IPMA also obtains information about the current road from the navigation system through the High Speed (HS) Controller Area Network (CAN) comfort and chassis systems buses via the Body Control Module /Gateway Module (BCM/GWM) assembly. This data includes the current road speed limit, road type and country.

The IPMA combines the available speed limit information from both the navigation and vision systems, to provide a more accurate and consistently available speed limit value.

The speed limit value is sent from the IPMA to the BCM/GWM assembly using the HS CAN chassis systems bus. Then from the BCM/GWM assembly using the HS CAN comfort systems bus the vehicle speed limit value is sent to the Instrument Cluster (IC) and Head Up Display (HUD) which displays the information to the driver.

To indicate how recent the information is, the displayed sign fades away in a series of steps as the distance increases from the location of the sign. The driver can also use the system to provide a warning of speeding, by configuring the system to flash the speed limit sign in the display when the vehicle exceeds the displayed limit by a set amount.

Speed alert can be switched on and off, or the settings can be adjusted by the driver to display three different settings:

• Vehicle speed equals the detected speed limit.
• Vehicle speed is 5 mph (10 km/h) above the detected speed limit.
• Vehicle speed is 10 mph (20 km/h) above the detected speed limit.

Rain and snow speed limits are indicated, when applicable, as are towing speed limits, when a trailer is connected to the vehicle. Speed limit information from the navigation system is displayed for roads with no sign information.

If the navigation system is not available, or the off-road navigation is selected, the Traffic Sign Recognition (TSR) system will use the camera only, but cannot perform to full functionality.

The system can be switched on and off via the Instrument Cluster (IC) message center menu. The system will operate up to a maximum speed of 155 mph (250 km/h).

The performance of the Traffic Sign Recognition (TSR) system may also be affected in the following conditions:

• During adverse driving conditions, if the camera has impaired vision (reduced visibility, less than 0.6 miles (1 km), for example heavy fog, rain, snow, or soiled windshield.
• Signs are rotated greater than 15 degrees in pitch, yaw or roll, compared to the road surface.
• Concealed or covered sign information.
• Non-conforming road signs.
• Accuracy and validity of navigation data (i.e. up to date).
• Traveling in an area not covered by the navigation system.
• Driving in direct sunlight, leading to overexposure and reduction in contrast.
• Vehicle not in a supported country.

In the event of a system fault, the feature is suppressed until the fault is rectified. The driver is informed via an Instrument Cluster (IC) text message and warning symbol.

 

Shows on the nav screen of my 2018 with ICTP. But I think mine gets it from GPS & maps, not reading signs - don’t have that option.

 

Same here.
