Any further thoughts on this? Is there possibly missing hardware?

Thanks

Does anyone know if "Country Road Assist" can be enabled in the CCF?

As far as I can ascertain, the Defender has all the required equipment and the bulk of the logic looks to be actually built into the NAV, which is present as the same logic is used for the ECO Coach.


COUNTRY ROAD ASSIST

Country road assist is only operational when adaptive cruise control is active. See ADAPTIVE CRUISE CONTROL.

Country road assist is an enhanced feature of the adaptive cruise control system. Country road assist alters the vehicle’s speed for upcoming road curvature or changes to the legal speed limit on the road ahead.

Country road assist utilises information stored in the on-board navigation system and the forward-facing camera to determine the correct speed for the road ahead.

Country road assist utilises information stored in the on-board navigation system to determine the curvature of the road ahead.

Country road assist incorporates two features to reduce the requirement of driver interaction with the adaptive cruise control system. The country road assist features are:

Corner speed adaptation – the feature identifies and reduces the vehicle speed to a comfortable value if the current cruising speed is too high for an upcoming corner.
Speed limit adaption – the feature identifies the upcoming speed limit and updates the adaptive cruise control set speed.

Limitations:

The corner speed adaptation feature may not always be available or accurate, particularly in the following situations:

If the road's course is not clearly visible.
If the road is narrowing.
On wet, icy or snowy surfaces.
While towing a trailer.
When the accelerator pedal is pressed.
When the driver deviates from the set route.
If a navigation system other than the on-board navigation is used.
If the navigation system's map data is out of date, unavailable, or inaccurate. See MAP UPDATES.
The speed limit adaptation feature may not operate in the following situations:

In poor visibility due to:
Insufficient illumination of the road, or
Variable shade conditions, or
Rain, snow, fog and heavy spray.
In areas of light glare, for example from oncoming traffic, direct sunlight or reflections.
If the windscreen in front of the rear view mirror is dirty, misted up, damaged or obscured.
If the traffic signs are not detected due to dirt, snow or insufficient lighting, or otherwise obscured.
When the driver deviates from the set route.
If a navigation system other than the on-board navigation is used.
If the navigation system's map data is out of date, unavailable, or inaccurate. See MAP UPDATES.
If the signs are ambiguous, for example in roadworks or signs in adjacent lanes.
During sharp turns when adjacent traffic signs are outside the camera's field of vision.
Varying maximum permissible speeds in individual lanes, for example at toll stations.
