Types of Bluetooth Adapters for Harley Davidson Radios
When you start looking for a Bluetooth adapter for your Harley, you’ll find there are a few main types. They all do the same basic job – getting Bluetooth into your bike’s audio system – but they connect in different ways. Understanding these will help you pick the one that’s right for your specific Harley.
1. Aux Input Adapters
This is often the simplest and most common type. These adapters plug into your Harley’s existing auxiliary (AUX) input jack. If your bike has an AUX port, this is usually the easiest route.
How it works: The adapter typically has a male 3.5mm jack that plugs into your AUX port. It also has a Bluetooth receiver that pairs with your phone. Some models have a small control module for play/pause or track skipping.
Pros: Very easy to install, generally affordable, preserves original radio.
Cons: Requires your bike to have an AUX input jack, might require a separate power source if not powered through the AUX connection, sound quality can depend on the AUX jack’s quality.
2. FM Transmitter Adapters
If your Harley radio doesn’t have an AUX input, an FM transmitter is a popular alternative.
How it works: This adapter broadcasts the audio from your Bluetooth-connected device over a local FM radio frequency. You then tune your Harley’s radio to that specific frequency to hear the audio.
Pros: Works with almost any radio that has FM reception, requires no physical connection to the radio itself.
Cons: Sound quality can be affected by radio interference and the strength of the FM signal, may require finding an unused FM channel in your area, can be less convenient than direct connection.
3. Direct Integration Adapters (for specific models)
Some adapters are designed to integrate more deeply with your Harley’s existing radio system, sometimes plugging into specific wiring harnesses or even replacing certain components. These are less common for aftermarket additions and more likely found as part of a radio upgrade.
How it works: These adapters often connect directly to the radio’s internal wiring or communication bus.
Pros: Can offer the best integration and audio quality, potentially unlocking more features.
Cons: Installation can be more complex, often model-specific, might be more expensive.
4. Handlebar-Mounted Bluetooth Receivers
These are standalone units designed to be mounted on your handlebars. They often have their own small speaker or can output audio to your existing system via an AUX input or FM transmission.
How it works: These units are self-contained Bluetooth receivers. They might offer basic controls and are visible and accessible on your handlebars.
Pros: Easy access to controls, can be used independently or to send audio to your bike’s system.
Cons: Aesthetics might not match all bikes, sound quality from integrated speakers might not be powerful enough for highway speeds.
Choosing the Right Adapter for Your Harley
To pick the best Bluetooth adapter, you need to know a little bit about your Harley’s audio system and what you want to achieve. It’s like choosing the right battery for your car – you need to match it to the vehicle’s needs.
Here’s a breakdown to help you decide:
1. Check for an AUX Input: This is the most important first step. Look for a small, round jack on your radio faceplate or sometimes near the back of the radio in the fairing. It might be labeled “AUX,” “Line In,” or have a headphone symbol. If you have one, an AUX input adapter is usually your best bet for straightforward integration and good sound quality.
2. Consider Your Radio Model: Different Harley models and years came with different radio systems. Some older bikes might not have any readily available audio inputs. Research your specific bike model and year to see what options are commonly available. Websites like RevZilla or forums dedicated to Harley Davidsons are great resources for this.
3. Determine Your Budget: Bluetooth adapters range from $20 for a basic FM transmitter to $100 or more for higher-end AUX adapters with advanced features. Decide how much you’re willing to spend.
4. Think About Sound Quality: If pristine audio is your top priority, an AUX input adapter will generally offer better sound than an FM transmitter, which can be prone to static and interference.
5. Ease of Installation: If you’re not comfortable with wiring or taking parts of your fairing apart, opt for a simpler plug-and-play AUX adapter or a wireless FM transmitter.
Compatibility Check: A Crucial Step
Before you buy anything, double-check that the adapter explicitly states it’s compatible with your Harley Davidson radio system or motorcycle model. Manufacturers usually list compatible models on their product pages. Don’t assume it will work! Many adapters are designed for specific radio interfaces.
Tools You Might Need for Installation
While many Bluetooth adapters are plug-and-play, you might need a few basic tools, depending on the type of adapter and your bike.
Screwdriver Set: You might need to remove fairing panels or radio bezels. Phillips head and flathead screwdrivers are common.
Plastic Trim Removal Tools: These are essential for safely prying off fairing panels without scratching your paint. They are much gentler than metal tools.
Wire Strippers/Crimpers (Less Common): For more complex installations where you might need to tap into power or ground wires, though most modern adapters don’t require this.
Zip Ties: To neatly secure any loose wires or the adapter unit itself.
Multimeter (Advanced Users): To check for power sources if needed, but typically not required for simple Bluetooth adapters.
Your Motorcycle’s Service Manual: If you’re unsure about removing fairing parts, this is an invaluable resource.
Step-by-Step Guide: Installing a Bluetooth Adapter (AUX Input Example)
This guide focuses on installing a common AUX-input Bluetooth adapter, as it’s one of the most popular and straightforward methods. Always refer to the specific instructions that come with your adapter, as procedures can vary slightly.
Step 1: Prepare Your Workspace and Gather Tools
Find a good spot: Work in a well-lit area, preferably with a stable surface to lay out your tools and parts.
Gather your tools: Have your screwdriver set, plastic trim tools, and the Bluetooth adapter handy.
Disconnect the battery (Safety First!): Although many installations won’t require full battery removal, it’s good practice to at least disconnect the negative terminal of your motorcycle’s battery. This prevents accidental shorts. You can usually access the battery under the seat. Consult your bike’s manual if unsure.
Step 2: Access the Radio and AUX Input
This is often the most involved part. On many Harley Davidson models, the radio is behind a fairing.
Remove Fairing Panels: Carefully use your plastic trim removal tools to detach the necessary fairing panels, dashboard covers, or speaker grilles that obstruct access to the back of the radio. Start from the edges and gently pry. Take note of where screws or clips came from.
Tip: Many Harley fairings have specific panels that need to be removed to access the radio mounting. Refer to your service manual if needed.
Locate the AUX Port: Once you have access, carefully reach behind the radio unit and look for the AUX input jack. It might be a single port, or sometimes it’s part of a larger wiring harness.
Step 3: Connect the Bluetooth Adapter
Plug it In: Insert the 3.5mm male connector of your Bluetooth adapter directly into the AUX input jack on your Harley’s radio. It should fit snugly.
Connect Power (if applicable): Some adapters are powered directly through the AUX connection. Others might have a separate wire for power. If yours needs a power connection:
You might be able to tap into an accessory ignition wire (a wire that has power only when the ignition is on).
Alternatively, some adapters come with a USB cable or a cigarette lighter adapter that you can route to a power source.
Ensure any power connections are secure and insulated to prevent shorts.
Step 4: Route and Secure the Adapter Unit
Position the Receiver: Decide where you want the Bluetooth receiver unit itself to be. Some adapters have a small box, others might be a small dongle. You want it accessible but not in the way.
Tidy Up Wires: Use zip ties to secure the adapter and its wires neatly behind the fairing. Avoid letting wires hang loose or press against moving parts. Ensure they won’t rattle or interfere with any components.
Step 5: Test the Bluetooth Connection
Reconnect Battery: Reconnect the negative terminal of your motorcycle battery.
Turn on the Ignition: Power up your Harley’s ignition and then turn on the radio.
Pair Your Device:
Put the Bluetooth adapter into pairing mode (check its manual for how – usually holding a button).
On your smartphone, go to Bluetooth settings, scan for new devices, and select your adapter from the list (it will likely have a specific name).
Pair your phone with the adapter.
Select AUX Source: On your Harley’s radio, select the AUX input as the audio source.
Play Some Music: Play a song or podcast from your phone. You should hear it through your Harley’s speakers.
Test Calls (if applicable): If your adapter supports hands-free calling, test making and receiving a call.
Step 6: Reassemble Fairing Panels
Once you’ve confirmed everything is working perfectly, carefully reattach all the fairing panels and covers you removed. Make sure all clips snap back into place and all screws are tightened properly.
This process can vary greatly depending on your specific Harley model and the adapter. If you’re unsure about any step, it’s always best to consult your motorcycle’s service manual or seek help from a qualified mechanic.
Tips for Using Your New Bluetooth Adapter
Getting your adapter installed is just the first step. Here are some tips to make sure you get the most out of it and keep it working smoothly.
Keep Firmware Updated: Some adapters have firmware that can be updated via a computer. Check the manufacturer’s website periodically for updates, as they can sometimes improve performance or add new features.
Charge Smart: If your adapter has a separate power cable (like a USB), ensure it’s connected to a stable power source that turns off with the ignition to prevent battery drain when the bike is off.
Protect from Elements: While most motorcycle electronics are somewhat weather-resistant, avoid leaving direct water exposure on the adapter unit if possible. Consider a small waterproof pouch or cover if it’s mounted externally and exposed.
Troubleshoot Connectivity Issues: If you have trouble pairing or maintaining a connection:
Ensure Bluetooth is enabled on your phone.
Try turning both your phone’s Bluetooth and the adapter off and then on again.
Forget the device on your phone and re-pair it.
Check for interference from other electronic devices.
Understand Volume Controls: You’ll likely have volume controls on both your phone and your Harley’s radio. Start with both volumes low and gradually increase them to find the best balance and avoid sudden loud noises.
Bluetooth Adapter vs. Harley Davidson’s Built-in Systems
Harley Davidson has steadily improved its infotainment systems over the years, with newer models often featuring Bluetooth connectivity built-in. So, why might you still need an adapter?
Older Models: Many beloved Harley Davidson bikes are older and simply weren’t equipped with Bluetooth from the factory. An adapter is the only practical way to add this feature without a full, expensive radio replacement.
Cost-Effectiveness: Replacing an entire original radio unit can be very expensive. A Bluetooth adapter is a much more budget-friendly solution for adding wireless audio.
Simplicity: Sometimes, you just want Bluetooth for music and calls, and a dedicated adapter offers a simpler, more focused solution than a complex infotainment system.
Preserving Originality: For collectors or those who love the classic look of their bike, an adapter that minimally changes the dashboard maintains the original aesthetic.
While Harley’s integrated systems are great, an aftermarket adapter serves as a lifeline for owners of older bikes, bridging the gap between vintage style and modern convenience.
Troubleshooting Common Issues
Even with the best setup, you might run into a hiccup now and then. Here are some common problems and how to fix them:
Issue: No Sound Through Speakers
Check Source: Ensure your Harley radio is set to the AUX input source.
Check Phone Volume: Make sure the volume on your smartphone is turned up.
Check Adapter Volume: If your adapter has its own volume control, ensure it’s not too low.
Check Connections: Verify that the adapter is securely plugged into the AUX port and any power connectors are firm.
Restart: Turn off the bike, cycle the ignition, and try again.
Issue: Bluetooth Not Pairing or Connecting
Device Limit: Some adapters can only pair with one device at a time. Ensure your phone is the only device trying to connect.
Clear Paired Devices: Your adapter might have a list of old devices it remembers. Try clearing this list (usually by holding a button for 10-15 seconds) and then re-pairing your phone.
Bluetooth on Phone: Make sure your phone’s Bluetooth is switched on and discoverable.
Proximity: Keep your phone close to the adapter during the pairing process.
Issue: Static or Poor Sound Quality (FM Transmitter)
Find a Clear Channel: Try tuning your radio to a different unused FM frequency that has less static.
Adjust Transmitter Location: Sometimes, moving the FM transmitter unit slightly can improve the signal.
Reduce Interference: Keep the transmitter away from other electronic devices that might cause interference.
Issue: Adapter Drains Motorcycle Battery
Check Power Connection: If your adapter is wired for power, ensure it’s connected to a circuit that only has power when the ignition is on (an accessory or switched power wire). Connecting it to a constant hot wire will drain your battery.
Use a Relay: For more permanent installations, an automotive relay can ensure the adapter only draws power when the ignition is active.
* Adapter Power Draw: Some adapters may have a higher quiescent current draw (power consumption when off). If all else fails, consider unplugging it when the bike is stored for long periods, though this is rare for quality units.
Always refer to your specific adapter’s troubleshooting guide for the most accurate advice.
