Auxiliary Input Jack for Car: OEM Aux Port Replacement by Model

If your car came from the factory with an auxiliary jack that stopped working, an OEM auxiliary input jack replacement is almost always the fix – not a new head unit and not a Bluetooth adapter. These small dash-mounted parts plug directly into your existing stereo wiring using the exact factory connector, so you get a stock-looking AUX button back with no visible wiring changes. Below are three OEM-fit replacement jacks, organized by the vehicles they actually fit, so you can match the correct part number instead of guessing.

OEM Aux Jack Replacement vs. Adding an Aftermarket Aux Port

These are two different repairs, and it matters which one you actually need. If your car originally had a factory AUX jack that has since failed, cracked, or stopped registering a connection, you want an OEM replacement part like the ones below – they use the same connector and mounting slot your dashboard already has, so installation is plug-and-play with no rewiring.

If your car never had a factory aux port at all, an OEM replacement jack will not help, because there is no matching wiring harness behind the dash to plug it into. In that case, see our guide on how to add an aux port to your car from scratch, or consider a Bluetooth AUX adapter if you would rather skip wiring entirely and connect wirelessly.

Reeoutdoor 86190-02010 Aux Jack Port for Toyota Tacoma, Corolla, and Tundra

This adapter is built for owners of the Toyota Tacoma (2009–2012), Corolla (2009–2013), and Tundra (2007–2013) whose factory stereo already has an auxiliary button on the dash that has gone dead or intermittent. Because it is a direct replacement for OEM part 86190-02010, it reuses your existing wiring harness and mounting slot – there is no soldering, no rewiring, and no need to open up the stereo itself.

Pros

• Snaps into the factory dash slot with no cutting or drilling
• Reuses the existing stereo wiring, so installation is closer to 15 minutes than an hour
• Correct fit confirmed for Corolla, Tacoma, and Tundra by the OEM part number match

Cons

• Will not fit a car that never had a factory AUX slot in the first place
• Toyota reused similar dash cutouts across other models, so double-check your year and trim before buying

X AUTOHAUX 39112-SNA-A01 Aux Adapter for Honda Civic 2006-2011

The X AUTOHAUX 39112-SNA-A01 is a direct match for the eighth-generation Honda Civic built between 2006 and 2011. Civic owners in this range are the most likely to run into a worn-out AUX jack simply because the part has been in service for over a decade, and Honda used this same connector across the whole generation, so fit is consistent regardless of trim.

Pros

• Installs without special tools – it is a straight swap for the failed factory part
• Confirmed compatible specifically with 2006–2011 Civic, so there is no guessing on fitment
• Restores full audio quality instead of routing through an FM transmitter or Bluetooth workaround

Cons

• Fits this generation of Civic only – not later or earlier Civic models
• Basic black finish only, no color-matching options

Auxiliary Input Jack for Toyota Camry, RAV4, Prius, and Lexus (2005-2009)

This adapter covers the broadest range of vehicles of the three parts on this page: the 2005–2009 Toyota Camry, RAV4, Prius, Yaris, FJ Cruiser, and 4Runner, plus the badge-engineered Lexus ES350 and LS460 from the same generation. It provides a direct connection for phones, MP3 players, and other line-level audio sources, which gives noticeably cleaner sound than routing audio through an FM transmitter or an old cassette adapter.

Pros

• One part covers both Toyota and Lexus applications from this model-year range
• Plug-and-play fit into the existing factory harness and dash cutout
• Cleaner audio signal than an FM transmitter, since it is a direct wired connection

Cons

• Not compatible with newer Camry/RAV4 generations that use the different 86190-0R010 connector
• Only replaces the physical jack – it will not add USB or Bluetooth if your factory stereo lacks those inputs

How to Find the Right OEM Aux Jack Part Number for Your Car

OEM aux jacks are not interchangeable between makes, and often not between model years of the same car, so it pays to confirm the exact part number before you order:

1. Check the connector on your existing (broken) jack for a stamped part number, usually printed directly on the plastic housing.
2. Look up your VIN on your manufacturer’s official parts site – Toyota owners can use autoparts.toyota.com and Honda owners can use hondapartsnow.com – to pull the exact aux jack part number for your specific build.
3. Match the connector pin count before buying: Toyota’s factory aux jacks typically use an 8-pin connector, while Honda’s uses a 5-pin connector, so a part built for one make will not physically plug into the other.
4. If the part number on your car does not match any of the three above, search that number directly on Amazon rather than assuming one of these three is “close enough” – a mismatched jack can fit the slot but fail to register a signal.

Frequently Asked Questions

What Is An Auxiliary Input Jack For Cars?

An auxiliary input jack allows you to connect external audio devices to your car’s stereo system. It enables you to play music or audio from smartphones, MP3 players, or tablets through your car’s speakers. This enhances your in-car audio experience with better sound quality and convenience.

How Do I Install An Aux Jack In My Car?

To install a replacement aux jack, first confirm the part number matches your car’s original jack. Then unclip the old jack from its dash slot, unplug the factory connector, plug the connector into the new jack, and snap it back into place. Finally, select the auxiliary input mode on your car stereo to confirm the connection works.

Are Auxiliary Input Jacks Universal?

No, auxiliary input jacks are not universal. Each manufacturer uses its own connector and mounting shape, and the same manufacturer often changes the part across model years, so a jack that fits a 2010 Camry will not necessarily fit a 2015 Camry. Always match the part number to your car’s specific model and year before buying, rather than assuming a jack labeled “for Toyota” will fit any Toyota.

Can I Replace A Faulty Car Aux Port Myself?

Yes, replacing a faulty aux port is a beginner-friendly repair for most owners. Purchase a replacement that matches your car’s exact OEM part number, unclip the old jack, transfer the factory connector to the new one, and snap it back into the dash. If you are not comfortable working around your dash trim or stereo wiring, a car audio shop can usually swap the part in under 30 minutes.

Why Isn’t My Aux Jack Working?

If your aux jack isn’t working, check for loose connections or damaged cables first, since a worn aux cable is a more common cause than a failed jack. Confirm the external device is playing audio and that your car stereo is set to the correct auxiliary input source. If the jack itself is cracked, loose in its housing, or no longer clicks when a cable is inserted, the jack has likely failed and needs the kind of OEM replacement covered on this page.

Is an OEM Aux Jack the Same as a Bluetooth Adapter?

No. An OEM aux jack is a physical, wired replacement part that restores your car’s original 3.5mm port using a cable. A Bluetooth adapter is a separate, standalone accessory that streams audio wirelessly and does not require your factory aux wiring to be present or working at all. If your factory aux jack is damaged beyond repair or your car never had one, a Bluetooth adapter is usually the simpler fix.

Conclusion

Choosing the right OEM auxiliary input jack comes down to matching your car’s exact part number, not just its brand. The Reeoutdoor 86190-02010 covers Tacoma, Corolla, and Tundra; the X AUTOHAUX 39112-SNA-A01 is built specifically for the 2006–2011 Honda Civic; and the RLP jack covers Camry, RAV4, Prius, and several Lexus models from 2005–2009.

All three are direct, plug-and-play replacements for a factory aux jack that has stopped working – no new head unit and no rewiring required. Confirm your part number using the steps above, and you can have your original aux port working again in about 15 to 30 minutes.
