Some portable audio equipment may be susceptible to certain types of electronic noisepresent in the vehicle's 12V power outlet.
Here are two ways to eliminate this type of interference:If the audio device is capable of being self-powered (battery), use it that way insteadof plugging it into the vehicle's power outlet.Have the customer purchase a Ground Loop Isolator, such as *Radio Shack Catalog #270-054.This device plugs in between the radio and the customer's audio device. It is packedwith one included Y-Adapter. If purchasing the *Radio Shack product, you will requirean additional Y-Adapter (Catalog #274-369). This device should be installed betweenthe audio player and the AUX input of the vehicle radio. These catalog numbers arestockednationally at *Radio Shack Retail Stores in the U.S. and are currently available.Other similar products are available through other electronics or car stereo retailersdefined as Ground Loop Isolators.Parts Information
