iPhone 4 suddenly changes volume in car

[airwalk331]

I have 32gb iPhone 4 with the Belkin TuneBase Direct iPhone car dock in my 2008 Honda Civic LX.

The dock charges my phone and plays it through my car stereo via aux-in.

Whenever I reach around 65-75 MPH the volume will suddenly dip and then go back to its original volume. I notice that when this happens, the volume bar on the screen of my iphone will go down and then back up.

Does anyone else have this problem? I'm wondering why is this happening and how I can fix it.

Any help is appreciated!

I know that some car audio systems automatically adjust volume based on speed due to increased cabin noise. I don't know if your car is equipped with such, but if so, could it be that the system is acting up?

In either case, I would think it would be more likely that it's something in the car's system rather than the iPhone.

Have you connected any other audio source to your honda and tried it under the same conditions?

My car does have that same system. I'll try turning it off and see if that helps.

Thanks!

I do know the phone volume will also dip slightly if an email or message comes in, causing a noticeable volume decrease for a second before returning to normal. Don't know why this would coincide with your speed, or it may just be coincidence. Is your car emailing you to slow down?

Haha, yeah I'm not getting any text or email when the volume dips.

So I turned off the Speed Volume Control option on my car stereo and the volume still dips.

Anyone else have any suggestions?
