Sep 26, 2008 As we discovered when we reviewed the Nuvi 260W and 760, Garmin has a very good safety camera warning system, which will alert you to upcoming red light and speed cameras. With a subscription, your Garmin device is linked to the Cyclops database, which is maintained daily and contains information about fixed red light and speed cameras. Regardless if you are exceeding the posted speed limit or not, your Garmin device will sound an alert as you approach a camera.
Hmm, this may not be what you want. Go to: and click Accessories, then click Safety Cameras. The 3597LMTHD is compatible with many Cyclops files but the US/Canada Cyclops is suspiciously not mentioned. If you decide to try it, definitely try the trial version before paying for a subscription: especially since the 3597LMTHD is not in the US/Canada list of the file's Compatible Devices although the non US Cyclops files do list the 3597LMTHD as being compatible.
Update: Found on page 4 of the thread: by mmoonitz on 4/17/13: Their cyclops 'app' will not work on their new 2797, nor ANY of their 2013 models, accord to tech support. Tried it and it wouldn't load. The POI Factory's loaded fine and their instruction was great. Tried it out last night, worked fine. Given that finding, may I suggest you try the redlight and speed camera files here.
