I was really starting to love my 8110.
That is until I drove home the other day and figured I would hook it up to my car stereo (through one of those tape adapter things) to listen to some music. It sounded fine overall, but every few minutes it would make the speakers in the car start buzzing for a few seconds. Then it would go away and start up again a few minutes later. I tried moving it farther from the console but nothing.
It was the same RF interference that I was getting through the work PC speakers, but even worse because the interference was being broadcast through the speakers much louder. The buzzing on the PC speakers was bad enough, but the car situation down right sucks.
I was planning on using the phone as also a convenient MP3 player in the car.
On a secondary sound issue, I was getting quite a buzz from the built-in speaker on the phone when I was talking on it. It was one of those rattling sounds that you hear on some cars where the stereo is too loud and the license plate in back is rattling back and forth. Same deal here - to slightly resolve that issue, I put in some padding in the battery compartment cuz it sounded like the battery cover itself was vibrating with the speaker (even though the cover is not loose). It helped slightly.
This is quite the noisy phone (both in terms of sound and RF interference).
