A:Answer I've had similar problems with the JVC unit as well, but it's when my phone is connected to the unit, either through the wire or bluetooth. If you have your Iphone attached to the unit, make sure that in your bluetooth settings for iPhone, you only have 1 "KW-V830BT" listed and not several. If you have several, delete the ones that you're not using. So far that has seemed to solve my problem.
