I have a Hum device in one of my cars. Everytime when I want to track the car, it is able to show the car location, speed, diagnostic information for few minutes. But then it is unable to locate the car and the % it is not able to locate the car is more than I pay for it. About 95% of the time, I am unable to locate the car, even if the car has not moved or anyone has touched it or tampered with the connection between my Hum and the ODB II ports etc.
Can someone shed light in to this as to how reliable is Hum Device?
