I have a Motorola BN61 from 10 months ago and for some reason about 5 months ago it had an off and off stage of charging my phone. First thing you know it, it is charging, next thing, it is not. And now when I got home it didn't work at all. What happened? A tag on the cord says ''For Warranty Replacement, Call 1-866-406-5154' Will they replace it since I had for 10 months? I am not for sure about this stuff.
