The BT connection can be effected by interference from the antenna

 

I don't think I need to prove facts. BT is a complete low power RF radio transceiver in a chip mounted on the OnStar circuit board. The antenna is inside the chip, thus it is tiny and buried in a box in a compartment. The BT in your phone is the same thing and it can be blocked by something as simple as holding the phone. The BT radio operates on a frequency band of 2.45 GHz, which is reserved for "industrial, scientific and medical devices". A Pacemaker could conceivably interfere with the signal, your wifi can interfere, a microwave machine can interfere, another BT device in use nearby can interfere, garage door remotes, wireless routers/receivers etc.

It is a very low power device operating on very crowded frequency band. Pretty much everything RF not on TV or telephone is in the same frequency.

 

No one is obligated to "prove" their information. Information is given, you can then research it, and decide whether to believe it or not.

this may explain somewhat

 

Obligated ?
Trying to learn and need advice on something I don't know about.
Info is given?
Then direct me to it.

 

Thanks Blue will read though this.
