My daughter's 2004 Corolla has a problem where when her phone is plugged into the 2Amp USB port on a car charger, the Radio won't come on.We have tried multiple chargers so we know it is not a defective charger. If she were to plug into a 1Amp USB charger the Radio works fine! The cigarette lighter port is rated for more than 2Amp draw so thinking that something is wrong. I know they are on the same circuit. I assume there is a voltage drop, but not sure where to even start looking for it. Any suggestions? Is it likely to be a ground connection? Back of the radio, wires to the lighter, etc?
Anyone see something like this before?
Thanks.
