Rear Camera Post-pass Hold Distance (m)

AutoNaviRearCameraHoldDistance

When external navigation reports a rear speed or rear signal-and-speed camera (TMAP 75/76), retain the target-speed cap for this distance beyond the camera. The position is captured within the final 50 m and tracked by traveled distance even when guidance disappears or changes to the next item. Units are meters; 0 disables the extra hold. Increasing the value holds the cap farther beyond the camera. Stopping does not consume the distance. Disconnection, off-route status, or a new navigation session clears it. This distance does not apply to stock CAN warnings because their rear-camera type is not identified. Countdown completion does not end the speed hold.

Behavior

When external navigation reports a rear speed or rear signal-and-speed camera (TMAP 75/76), retain the target-speed cap after passing. Increasing the value holds farther beyond the camera; decreasing it releases sooner. Zero disables the extra hold.

The position is captured within the final 50 m and tracked by traveled distance. The hold survives guidance removal or a switch to the next item, and stopping does not consume distance. A lower speed required by another control still takes precedence.

Usage

Displayed and stored values are in meters. The countdown ends at the camera; rear-camera hold distance is displayed separately. External disconnection, off-route status, a new session, a traveled-distance reset, or disabling camera control clears the hold.

Reference

Stock CAN does not identify rear-camera types, so this extra distance does not apply to it. The configured distance does not guarantee that measurement by the actual camera has ended.
