Hi,
I recently bought an XLI loaded with Star Tracker System. Having transferred the tracker to my name, I contacted their operations to ask the current location of my car, they told me that it is not possible for them to tell the exact location of a vehicle! Their system works on GSM based signals, that means they are only able to know only which is the nearest tower to a vehicle or vice versa.
I then requeted them to tell me if the system on board of my car is running smoothly, which they instantly told me in affirmation. To further confirm, I asked them to send any signal to my car, either immobilize it or blow its horn. They said OK they are sending the command to my vehicle to blow its horn. I, very enthuiastically, called my watchman and told him in an impressing tone that "Look my car is going to blow its horn automatically on the remote signal which is going to be sent wirelessly by the company. And told him to immediately tell me as the horn blows, he got very impressed and told me that he will do exactly as told.
Its been 12 hours, he and I am still waiting for the signal ...
