Overview: The TYTO-01 interface is designed to allow you to replace the OEM radio with an aftermarket head unit in select 2001 and later Toyota and Lexus vehicles and retain the use of the JBL and JBL Synthesis amplified audio systems. Please consult Crutchfield's Outfit My Car to see if your vehicle is compatible.

Connections: The TYTO-01 interface module includes a 14-pin to 20-pin Toyota/Lexus harness which plugs into the TYTO-1 interface module and your vehicle's factory radio harness. This same harness also has 12-volt constant (yellow), 12-volt accessory (red), ground (black), and illumination (orange) leads that tie into your aftermarket head unit's harness. The interface also includes a 16-pin harness which plugs into the TYTO-01 interface module and is wired to the remote turn-on and speaker level outputs of the aftermarket head unit.

05 Tundra

Written By Chad05Tundra, illinois on Monday, December 29, 2014

Crutchfield Customer Review (What's this?)

Easy to follow instructions. Pictures were clear and instructions referenced diagrams that made understanding much easier. My radio had two plugs, and the adapter harness only referenced and utilized one.

Pros: Color matched and easy tip follow instructions.

Cons: One wire not used or referenced. Sounds pot adjustment a pain.

Easy Install

Crutchfield Customer Review (What's this?)

Easy to install. Just match colored wires with your stereo. Check out YouTube for advice. The connector to the car's harness was a bit of work to connect, but finally got it. Makes the whole install easier. Don't pay full price.

Simple install. Gave it 4 stars b/c it did not supply a Illumination wire, but called Crutchfield and tech was able to give me the color code to the factory harness that i could tap in to.

Pros: simple install

Cons: lack of illumination

Crutchfield Customer Review (What's this?)

Pretty good part, very easy installation since it comes with RCA connector. I did not even have to worry about ripping/soldering cable. just plug & play.

Pros: Easy to install, well-labeled on individual wire.

Cons: If it came with written instruction paper, it should be perfect!

Axxess TYTO-01 Toyota Factory Integration Adapter - Product Review

Written By cruthikloyalty, Middlebury, VT on Tuesday, May 21, 2013

Crutchfield Customer Review (What's this?)

Great product, makes installation seamless and eliminates having to cut your factory harness.

Pros: Product is as advertised. At the discounted price this product is worth the money.

Cons: Does not offer enough channels to handle all speakers in my vehicle (Lexus RX) when you adjust the settings for sound from front to rear and left to right certain adjustments do not play sound where it should be. I have checked my installation of connecting the wires multiple times so its not an installation error.

It works!

Crutchfield Customer Review (What's this?)

I am very pleased with the quality of this product. The only thing I could do better would be to replace the factory speaker system, which is not worth the hassle. I am thinking of usign this in another one of my Toyota vehicles.

Pros: Ease of installation, clear concise instructions.

Cons: None that I can recall.

Crutchfield Customer Review (What's this?)

Product works as described once pin was reinstalled in car side connector. Was able to find this same product for less than 50$ on amazon so maybe you should try price matching too some extent and I would def purchase more from y'all.

Pros: Works

Cons: Pin in harness had to be reinstalled and product was overpriced.
