Abstract

Substantive informational conflicts as between navigation information provided by an in-vehicle navigation unit (101) and an in-vehicle roadside information service receiver (107) are detected (203). When detected, information from one source or the other is modified (207). Such modification can include alteration and/or deletion of one information item or the other. The modification can alleviate the conflict and/or otherwise provide alternative information to a user of the vehicle to support journey goals.
