easy to wire, easy to install

Written By Anon, North Carolina on Friday, November 20, 2015

Crutchfield Customer Review (What's this?)

This interface (unlike the PAC SWI-RC, which I installed at the same time) has clear instructions and is easy to wire and install. Wires are conveniently pre-stripped. Some wires from the aftermarket radio connect to different sides which makes for slightly more of a rat's nest than it strictly needs to be. But on the whole a good product.

One of the easiest harnesses I have worked with.

Great Product, Easy to install

This product came with very clear, easy-to-understand documentation, and was very install to install.

Pros: Great documentation, easy to install

Cons: None

Scary at first, but pretty easy overall

Written By Pablo O, California on Friday, November 13, 2015

Crutchfield Customer Review (What's this?)

When I got it and started reading the instructions I was a little overwhelmed at first. I had also bought the steering wheel control kit as well so it felt like I had a mess of wires. After I sat down with my head unit (Kenwood DNX 692) and laid everything out I did a dry run and felt much more at ease. I decided to go with a soldering iron and and heat shrink to cover the soldered pieces. A little tedious but it turned out great. Everything went together and works great

Pros: Colors are well matched to standard colors, instructions are fairly clear, plenty of slack on wires

Cons: Could use some double-sided tape to mount in dash

Exactly as advertised

Confusion with light-green wire

Written By MikeD, San Marcos on Thursday, August 27, 2015

Crutchfield Customer Review (What's this?)

The instructions tell me to tape off the light-green wire on the adapter, as it will not be used. On the stereo is a light-green wire to be connected to the parking brake wire sensor. I called tech support and was told to connect it to the light-green wire on the adapter, which I did; unfortunately, this didn't allow me to use the features when the emergency brakes are engaged. I called again as was told by support that the wire was supposed to be connected to the red (with white stripe) wire located above the pivot of my pedal emergency brake. Other than this issue, the install was flawless.

Pros: N/A

Cons: Confusion with light-green wires between stereo and adapter, which are not supposed to be connected

Crutchfield Customer Review (What's this?)

Instructions good, connections worked as necessary - only complaint is that the pieces to crimp the wires together are not included in this kit - why not?! Was hoping for a complete installation without a trip to the hardware store.....

Pros: instructions good, connections worked

Cons: no pieces to connect the wires in the kit?! This needs to be changed or something noted during the order process that these must be purchased separately.

Great except for one issue

Written By Chado, Vancouver, BC on Monday, May 04, 2015

2007 Lexus RX400h there are eight speakers driven by the factory amp (which is a pioneer type D amp) over six outputs. From the TYTO-1 there are four speaker connections from your new headunit to the amp, FL, FR, RL and RR. This is what I expected the TYTO-1 to sort out, the four input to six output issue.... but it did it backwards. Let me explain, from the amp there are six outputs, two outputs drive the left and right 3/4" tweeters and 3" midrange speakers (which are wired in serial), two outputs drive the front door left and right 6x9" woofers and two outputs drive the back door left and right 6.5" speakers. This actually makes for a pretty good setup if it works properly as you have your front six speakers setup up to create a better sound balance. With the factory headunit, I imagine this is what is happening. However, this ability to balance the channels is lost with a new headunit and the TYTO. Instead, because the headunit and the TYTO only allow for four outputs, the Axxess actually controls and rear door speakers and the front door woofers as if they are both rear door speakers!! I realize that without a headunit with a minimum of six speaker outputs, true control of all three channels on the amp is impossible, but i assumed that at the very least the TYTO would be smart enough to pair my front speakers together and not split them apart to be paired with the rears!! Not a smart setup. Btw, always solder your wires.

Pros: Easy setup, instructions were great except for a typo that said 20-pin harness instead of 14-pin harness.

Cons: Pairs front woofers with rear speakers.

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

Written By Dave, Helena, MT on Friday, December 05, 2014

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 Hookup

Crutchfield Customer Review (What's this?)

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

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.

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.
