Some portable audio equipment may be susceptible to certain types of electronic noise present 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 instead of 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 packed with one included Y-Adapter. If purchasing the *Radio Shack product, you will require an additional
Y-Adapter (Catalog #274-369). This device should be installed between the audio player and the AUX input of the vehicle radio. These catalog
numbers are stocked nationally at *Radio Shack Retail Stores in the U.S. and are currently available. Other similar products are available through
other electronics or car stereo retailers defined as Ground Loop Isolators.
