The point is that the transmit power of a phone is very low, and I like to believe the circuits in the car are protected (grounded) enough that the radio waves of a phone would not affect them. If the phone is a problem for the car, then lots of other radio wave sources would be a problem too.

You raise a very good point of the frequency. Even at a low power -- the FM radio station and the radio receiver -- great things happen at the correct frequency. You bring order back to my universe though when you talk about sheilding. Thank you.

When you stop saying things like this, I won't need to keep pointing them out: "Sometimes I look for things of comfort under my rock, please do not disturb the yen and the yang." |
