I just got the bluetooth headset, nokia one, for the N810, and every time there is a sound initialised through the n810 into the headset, the headset makes a beeping noise. The battery is fully charged, and i suspect its a "feature" of the headset? What it means is that when i'm driving and using the Wayfinder Navigation, i'm missing some of the direction instructions because the "beep" noise cuts out the voice for at least a second. Is there a fix for this, or is it always going to be like this, because if it is, its ****.
