red light cameras and school zone crossing

The good news is that various threads here at The Factory indicate that Garmin's POI Loader program will load Custom POIs to a Kenwood KNA G510. If you have any issues, do a search here for that model:

Given this, I expect The Factory's Redlight and Speed camera POI files can be added easily and work for you.

School Zones aren't as simple.

Regarding School Zones, there are a small number of local regional school zone files that might be of use to you:

I see that there is an Arizona School Zone file available from 2008 but I haven't used it to see how complete it is and how it works for alerts. From the thread discussing this file, I have the feeling that the POI locations are the actual school buildings rather than roadway school crossings and this can create a problem discussed below regarding the need for TourGuides.

A better nationwide "School Zone" file can be created for Garmin nuvis by using the large "Schools" POI file and setting it as a TourGuide. You need to check the above search and see if the Kenwood can do TourGuides--I found no info on Kenwood and TourGuide. For creating a School Zone POI with the Schools POI file, scroll down to my reply of 8/19/12 in this thread:

My method using TourGuides on nuvis absolutely requires an audio alert to be included, meaning that for devices using wav files, that sox.exe is required when installed with a PC, etc.:

Good luck, have fun, and drive safely
