I purchased a 2004 SRT 10 with factory installed radar detection last fall. The device is constantly going off warning me of signal detection to the front or, to the rear. I've had detectors before and know that they pick up a lot of errant signals but, this one talks. It's loud as hell. Has anyone with this type of detector (don't know the brand) been able to control the volume of the device? I don't have an owners or manufacturers manual, so need advice from someone familiar with the device.
