I'm looking for a GPS app that I can mark speedtrap locations and have the program alert me as I approach the area. There is a stretch of road I drive (Ortega Highway) that I want to map out the LEO hiding spots. There is no cell signal on my phones for a good section of the highway. I was thinking in the line of something like Trapster but where I can add permanent POIs for the trap spots. Trapster doesn't work in that area due to no cell signal, nor is it updated enough to rely upon. So I guess I just need a basic GPS program that I can add POIs and that will announce them as I get close to those POIs. I have a 9500ix that I can use to alert me of custom spots I mark but I prefer to use my V1 in that area. Don't want to have the 9500ix and V1 both running together and interfere with each other. Due to the use of IO on that highway, I don't want to rely on the 9500ix which is not so hot in picking up IO stray signals. So the V1 is my preferred RD to use. But I can't remember all the hiding spots without some GPS help.
