Question about Sony -Ericsson OEM HCB-300 Bluetooth Handsfree Car Kit Headset
The main question is about the power supply and especially with the 12 volt dc and the 12 volt ignition.
Maybe the car kit has been installed without taking account of the 12 volt ignition which is important to unpowered the kit and preserve the product more longer.
Sometimes no ignition on the key.
I do not know what sign on the sony, but in some vehicle on the market you have to inverse fuses to make it working longer.
Some of the car kit can work during a certain time, but a day to an other will not working any more.
