Valentine One is the greatest radar locator of all time. I bought one in 2002 and have upgraded it twice since then. The V1 doesn't become obsolete. You can have it updated when new features are released. Personally I wouldn't rely on GPS to block false alarms. Yes the V1 is chatty at times so I know were every motion and speed sensor is located from home to work and everywhere else. The V1 has paid for itself several times over in the years that I have owned it.
