    Does somebody have a car radio installed that goes louder when there is more outside noise, for instance when you go on a motorway or drive with the roof down?

    And what's your experience with this system?

    I've had cars that increased the radio volume as you increased speed, when obviously there would be more noise in the car.
    It's an option in the radio, but I've only seen it on radios that were built into the dashboard of the car. Those radios must have been linked to the cars ECU to know how fast you were traveling & automatically turn up the volume.
    I always turned the option to increase volume off, preferring to make my own changes when needed.

    If the method is linking to the ECU and not a build-in microphone, it would indeed explain why I can't hardly find any radio with that function. Because every car manufacterer probably uses a different ECU connector.

    Iv'e done the link to the ECU to the radio.
    Have a look here.

    You have to cut the wire, and join it (no 'plug and play' I'm afraid).

    "a build-in microphone"
    I don't think that would work; as follows:
    turn radio on at normal volume
    cars gets noisey at speed
    mic senses higher volume and turns radio up, so then...
    mic senses higher volume and turns radio up
    mic senses higher volume and turns radio up
    mic senses higher volume and turns radio up
    mic senses higher volume and turns radio up
    mic senses higher volume and turns radio up
    mic senses higher volume and turns radio up
    mic senses higher volume and turns radio up

    Does seem silly I agree :)
    But something like it does exist. Bose audiopilot uses a microphone in addition to a vehicle speed link.

    I was driving along a less than perfect road surface today singing along to a Roxy music cd and suddenly realised my voice had a strange vibrato.
    I felt as though I was using one those road breakers, I could feel the vibrations into the pit of my stomach. Now I'm thinking about changing the shock absorbers to try and soften the ride.
    I'm not bothered if the car loses some of it's gokart like handling, the suspension is so hard on the Copen that it must be doing damage to the car with the constant thuds it receives. If anybody has changed their shockers I'd be interested to read what happened.:)

    The Honda beat had this on standard stereo as far back as 1991.
