XM Radio

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.
