Retain your vehicle's factory features with a new radio

You want to install a new car stereo in your Toyota or Lexus, but you don't want to lose the useful features built into your factory radio. The Axxess AX-ADTY01 interface harness works directly with the AX-ADBOX1 interface to give you the ability to connect your new radio to the existing wiring in your vehicle and keep your factory features working. You'll keep the features you've become accustomed to, such as Bluetooth®, safety warning chimes, and Retained Accessory Power (RAP).

Important Installation Notes: You must use this harness with the AX-ADBOX1 interface to install your car stereo.

Please enter your vehicle information or call an Advisor at 1-888-955-6000 to find out if the AX-ADTY01 and its accompanying interface are compatible with your vehicle. Warranty: 1 year.

Note: Most vehicles will require additional installation parts — please identify your vehicle if you haven’t done so. You can also call an Advisor for more information.

Works and don't work?

Crutchfield Customer Review (What's this?)

Not hard to hook up!

Pros: Color coded right.

Cons: To bulky to hide needs improvement, be nice if they had some velcro to stick it to so it will be easier to tuck it all in.

2007 Tundra JBL Stereo

2007 Toyota Tundra
Crutchfield Customer Review (What's this?)

This harness made intstallation a breeze with all of the axxess components for factory powered amp amp and steering controls. There are three white factory pugs on the harness but you will only use the two that fit. Everything works great but there is a design flaw for a non needed plug.

Pros: Very easy, simple and clean installation for the tundra

Cons: Axxess needs to define harness and plug per vehicle type. so when you end up with a plug that is incompatible or does not fit the user will know.

Use a Harness, it's just smarter!

Crutchfield Customer Review (What's this?)

It just makes sense to use a harness rather than butcher your factory wiring. Think about the resale of the vehicle, you can take the stereo with you if you wish, or the next owner may want to replace what you installed. Butchering the wiring is not wise, in my opinion, these harness are worth the money!

Pros: Makes hook-ups easier, no need to look up what the factory wiring color codes are

Cons: None I can think of.

Axxess AX-ADTY01 with 2010 Toyota Camry with JBL

2010 Toyota Camry
Crutchfield Customer Review (What's this?)

This product simplifies installation. I installed this product in a 2010 Toyota Camry with JBL System. All the work wiring can be done ahead of time using this harness in conjunction with Metra's AX-ADBOX1 Interface Box and ASWC-1 Steering Wheel remote. Together these items plug right into this car harness simplifying installation. One important note is that the illumination wire is not included with this harness so you'll need to tap directly into the car harness for illumination control. Crutchfield Tech Support emailed the car harness pin out and identified the correct wire to tap into for radio illumination. I used this product with an Alpine CDE-W235BT, stock JBL Amp, stock JBL speakers and it works fantastic.

Pros: Makes installation a breeze

Cons: No illumination wire.

Makes installation a breeze

2004 Toyota Tundra
Crutchfield Customer Review (What's this?)

This harness made installation of my new head unit a breeze. The harness snaps right into the factory wiring and after a few wire connections to the new radio wiring harness, you are done. Instructions sheet is very clear and easy to follow.

Pros: Makes for fast and clean installation like a pro even if done a novice like me.

Cons: There was one extra connector that was not needed in my installation. I wish there was something in the instructions that tells me that so I wasn't wondering if I missed something.
