Bluetooth Call Feedback - '13 Denali

[jessalynn87]

My husband and I have noticed a faint whistling in the background on the opposite end of phone calls while driving the truck. (He hears it on his end while I am the one driving and vice versa).

The person in the truck does not hear anything, and no windows/sunroof are open....any suggestions?

It doesn't sound like typical feedback noise, it is very clearly a whistle, and just faint enough to be annoying without overtaking the rest of the noise/conversation in the vehicle, but not with any rhyme or reason to speed or acceleration patterns either.

Could be the coax cable going bad from water intrusion, however slight.

Where would that be located?

Right over your head, under the shark fin antenna. Mine has been throwing codes for about a year now and acts up occasionally; usually after a lot of rain. If you know someone with a scan tool that can read BCM codes, ask them to have a look.

Any other suggestions on this one? We have the same issue on our 2013.
