Anytime. The number of cameras seem to be growing exponentially especially in London where I live. Being aware of where they are ahead of time is really useful. Best wishes.

Hi David. When you buy a Zumo 590LM (or most other Garmin Devices) it comes with a safety camera database pre installed. The reason you should consider purchasing a subscription is because this database eventually goes out of date. The teams managing the road network move cameras around (both mobile and fixed) and average camera zones change also. If you have a subscription you can update the database to the latest version and be current. This is useful for two reasons. Firstly you have the new camera locations and secondly where an average speed restriction has been removed, that alert will be removed. For example in this video kzfaq.info/get/bejne/ocuDes1l286sf2w.htmlm18s the stretch of road on the second part has changed, it is now an average camera zone all the way into London and some of the fixed cameras have been removed. If you are using an out of date camera database the Garmin will only alert you of the now redundant fixed cameras and won't warn you of the average speed check. Similarly on the M3 out of London there were road works and an average camera zone for about a year but that has all been finished now so there are no longer speed restrictions on that stretch of road. If you are running the old database the Garmin will warn you incessantly that you are breaking the speed limit in an average camera zone even though it has been removed which is really irritating. I find having an up to date database particularly useful on the Motorcycle as it's easier to get caught out with the bikes acceleration.
