Strange.

When driving the Vette, if I make or receive a call on my cellphone the person on the other end can not hear me. I asked my wife if she could just hear the exhaust and it was drowning out my voice. She said that it's more like I'm talking through a cup with a string. This only happens in the Vette. I can drive the same exact road at the same exact time with the VW and don't have a problem.

What could cause this? I had the ICM checked and it tested good. Could the HEI coil be going and cause that sort of disruption?

I don't really care if I figure it out for the sake of the phone calls cuz they disrupt the Magnaflow symphony. But I just want to make sure there's not something electronic about to go out.

What type of phone? Are you using an ear bud of any kind?

First off, I don't think anything in the car is interfering. That would have to be in the 2giga htz range, and the car can't produce that kind of frequency.

If anything, it is the acoustics of the cabin. I would suggest you try the Jawbone. It does as good as job as any to kill outside noises.

It's a Samsung android phone. No bluetooth or headset.

It's just ironic that it only happens in the vette.

Remember... the sound inside the cabin is strange at times... They are not quiet and I wonder if the frequencies are messing with the microphone.

It could be that. My radio doesn't have any problems picking up stations.
It would be funny if the Magnaflows are causing since we've all been complaining about how loud they are.

What I am saying is that the resonance frequencies inside the cabin are messing with the phones microphone. They have noise killers and the circuitry might be getting confused.

So maybe if I disable the "voice privacy" feature it will help?

I'll have to experiment with mine. I haven't noticed any problem yet but I don't chat much while I'm driving. My HU has bluetooth to link my phone, so I plan on using that too.
