Help with mysterious unwanted incoming Bluetooth phone calls

[briandunning]

Our 06 nav Bluetooth system is paired with my wife's Sprint Samsung MM-A920, and everything works great.

However, every few minutes - literally - we get an incoming call. One ring only through the car's speaker, and then "call terminated by network." The phone's log shows nothing, as if the call never happened. Occasionally the caller ID on the car's screen shows 333, but usually nothing. My wife says that these calls always happen at the same place on the road - possibly near a cell tower, my guess?

Too annoying to live with, and I can't even remotely guess at a cause or a solution. Anyone have a suggestion, or a similar experience?

Do you have Sprint service as well? If so, try having your phone paired to the nav and drive through the same area and see if the same problem occurs. Sounds like a crazy RF glitch. I know that once at work, a RF tester cable was bad and RF signal was leaking out causing weird behavior on phones near by.

If you have the location of where it's happening, you can goto a Sprint Store and have the rep look up that location and see if it is a tower located there.

Although there are certain places where it happens nearby, it also happens everywhere else too, even out of state. For example a drive from LA to San Francisco would produce a hundred or more of these one-ring calls.

San Francisco might seem like it's in another state (maybe even on another planet) but it is still all California.

That's the new gov't tracking system. They regularly place a momentary call to your cell and triangulate your position for surveillance, though it's not supposed to actually ring. Maybe the bluetooth is detecting the signal and preemptively ringing before the phone tells it to ring.

Can you think of why "they" may be tracking you?

Just kidding... but that is how cellphones can be tracked.

You might want to re- pair your devices, and be sure to use a password/key and encrypt if all items support it.

Good luck.
