CB and cell phone won't get along

Hi all,

Have a small problem I can't find the solution to. Here is my set up:

2012 Mack Pinnacle
2 Wilson 2000's on stock mirror mounts with stock antenna cables
Cobra 29 LX peaked and tuned from DBT Radio
Astatic mic

I have Sirius/XM plugged into the stereo using the aux cord/ports. While this is plugged in everything works as it should, no problems.

When I plug the aux cord into my cell phone to play music from there I get a super high pitched squeal thru the truck speakers and the CB speaker. First time it happened I had the phone plugged into the charger so I unplugged it and turned the volume down on the radio and CB and it seemed to partially fix the problem (still there but not ear splitting).

Well that "fix" was short lived. Now if I have the phone plugged in at all I can't use the CB unless I unplug the aux cord.

Any help would be appreciated. Thanks

 

Awesome, I'll give one a try. Hopefully that'll fix it!

Thanks!
