Hey all,
Posted this at e46fanatics, but wanted to try here as well since I've found this site to be a bit friendlier.
I've had a Dice Mediabridge in my '04 330ci for about a month now. Really liking it. Interface is great, functionality is great.
The only issue I have is that when listening to my iPhone via USB, there is a regular "chrip" noise. The "chirp" itself probably lasts 0.2 seconds or something like that and repeats at about a 1hz frequency. I.e you'll hear something like 60 chirps per minute. In between chirps, there is basically 0 noise in the system (no hiss or anything else like that). The chirp unaffected by road speed or engine speed (i.e. neither the frequency nor the volume changes).
Compared to the volume of the music, the chirp is pretty muted. So when listening to rock it's not terrible. But for classical or anything that has low-volume sections or pauses, it's pretty annoying to hear that chirp.
This noise is not present when listening to the radio.
Any thoughts?
Thanks in advance.
