I connect my nokia n800 to the line input of my car stereo (the factory one) and I don't hear such a high level of noise. The sensitivity of the line level is quite low (as reported by many users on a forum dedicated to my car model, so it's not a tablet problem), so I have to crank up both the tablet volume and the stereo volume, this in itself isn't a big problem, the problem is when I switch to another source (radio or cd) forgetting to turn the volume down ;-). Once I had a loud thumping noise while charging (with a cheap car charger) and it turns out the audio jack wasn't fully inserted in the socket. Bye. -- Luca
