If you are having problems using your RediRad™, the following information will help you get things sorted out.

First, please read (or re-read) the owner's manual. It plainly covers proper installation and mobile device settings. If you've lost the owner's manual, you may download a copy of the current owner's manuals by clicking on Owner's Manuals at the bottom of this page. If you have an older AM-band RediRad™, consider sending it in for an upgrade – VERY worthwhile.

Section TWO presumes that your RediRad™ has been installed properly and that the radio and speaker are on and receiving local radio signals, but music from your portable device is not being heard.


Connect a pair of headphones to your mobile device, and play a song to verify that there's music playing.


Now connect the RediRad's™ audio plug to your device's headphone jack. Play a song. Set the device's output volume to 50% for AM-band RediRads™ and about 75% on FM-band RediRads™. Tune the radio to AM 1000 for AM-band RediRads™ and FM 91.1 on FM-band RediRads™.

If the broadcast radio signal doesn't disappear after a few seconds in RediRad™ mode:

  • Is power properly connected to your RediRad™? (See owner's manual.)

  • Are the batteries low on your mobile device? (This often requires higher output level for RediRad™ detection.)

If the audio quality on AM-band RediRads™ is either too quiet or distorted:

  • Confirm the tuner 'location' on the AM dial. Locate a broadcast radio station near AM 1000. At the top of every hour, the station is required by the FCC to announce its call sign and frequency. Note that number. For example, if the station you picked up is AM 960, you will need to adjust the tuner to the RIGHT (regardless of what the needle indicates) to get to AM 1000 to use the RediRad™.

  • If the music is too soft AND you are properly tuned to AM 1000, increase your mobile device's output volume until it is about the same level as the broadcast radio signals. After that, use the radio's volume control to increase it (not your device's output volume).

  • If the music is distorted AND you are properly tuned to AM 1000, decrease your mobile device's output volume until it is clear.

  • Note that if the tuner is NOT properly on AM 1000, a quiter and rather distorted version of what you want can be heard both above and below AM 1000.

Section THREEpresumes that your RediRad™ has been installed properly, that the radio and speaker are on and receiving local radio signals, and that music from your portable device is being heard – as well as electrical noise.

Filtering out electrical noise can be a project. For older vehicles, noise sources include the ignition wires, the generator commuator and regulator, and even the radio's power supply. For newer vehicles, high-speed digital signals are a key culprit. Adding aftermarket ignition amplifiers and other accessories to any vehicle can make matters even worse. We recommend that you obtain a copy of the chassis service manual for your particular vehicle.

On older (pre-1980) vehicles, three areas deserve your attention: Ignition & Charging systems, Grounding, and Radio Power Supply. On newer (1980+) vehicles, the ignition and charging systems still deserve careful attention. With the ever-increasing amount of sensors and computers added every model year, the integrity of vehicle grounding becomes even more important. Some things to consider:

  • Solid-core spark plug wires deliver a lot of spark but generate a LOT of noise. Shielding them helps when done right. Resistance-core plug wires greatly reduce radiated noise.

  • Replace old noise-suppressor capacitors (they look like condensers from a “points” set). A new condenser from a points set can be connected at the RediRad™ power connection.

  • Repainted vehicles often get reassembled without all of the braided ground straps that they originally had. So-called “star” washers cut through paint and do a good job of electrically bonding bare metal to bare metal.

  • Vacuum Tube radios emit a magnetic field that can be detected by AM-band RediRads™ (depending on the physical proximity or orientation of the RediRad™ relative to the radio's power supply).
