Yesterday I encountered a new Red Light Camera that my up-to-date database updated 9500ix did not alert me... there were flashing road work signs alerting of the RLC some 100 yards before the intersection... I'll see if this week's database update will include the particular location. For the last 8 months of owning ix this is the first one I noticed. Up until now, I have to say, I've been rather impressed by how promptly the new locations data were updated.
This encounter made me curious though... how are the location data collected/ entered into the database?
