You will need to buy a steering wheel control unit along with the headunit. Without that kit, the controls won’t work.

If the corolla steering wheel doesn’t have the controls and are color matched, you will need to purchase the S model or xle steering wheel and clickspring.

 

Roger on the need for the head unit and necessary control device. What was a surprise to me is the S and LE steering wheels are the same, see below. I was thinking an S had dual controls. And I will get whatever I need for the clockspring but there are 3 versions available according to the ‘Clockspring Experts’ link. I have written them a couple of times but have not heard back. While they highlight ‘choose wisely’ they do not provide a picture of each to help make that choice.

My hope is that someone out there has taken on this mod to add the second control and can provide the tips to doing this. The plugs on the new LH/RH control are pictured below.

Has anyone done it?

Thanks

DIY Steering wheel control add-on for CE/LE 2010 Corolla...

My car is a 2010 Toyota Corolla LE and after many months of research and frustration I've finally gone and done this mod with success! I would like to share my knowledge with all other Toyota Corolla LE owners who have wished for steering wheel controls. In a previous post I had noted that this...

Aces,
Thanks, and I have seen this excellent post. But it is about adding a single LH control to a vehicle that I guess did not have any before. His wiring diagram and competed pics show only the one LH control.

 

I’m not sure if the clock spring would need to be upgraded to add the Bluetooth controls. You’re likely going to need to find the car in the junkyard with the option and pull the wiring harness from it.

What Gen 10 Corollas had dual controls (LH/RH) on their steering wheel?

 

S, XRS and XLE.

 

Aces,
Thank you! When i looked at the S on line i did not see one with a dual control. I will look more.

 

It depends on the audio option. If it has the JBL or the nav, it’ll be part of that package for the Bluetooth.

 

As far as I understand it, the clock spring pinouts are different between a steering wheel with no steering controls, a steering wheel with steering controls on the left side, and a steering wheel with controls on both sides. Since you want to install the third option on your car, you need to find the clock spring off of a Corolla that came with factory bluetooth. Since I assume that you're in the U.S. market, the Corolla's that came with steering controls on both sides were JBL equipped S, XLE, and XRS models for 2009 and 2010, LE Premium package and S optioned with factory bluetooth for 2011, and all LE and S models for 2013.

Once you get that wired up, depending one what aftermarket headunit you choose you may need an adapter harness for those steering wheel controls to work with the headunit.

 

Aces,
Thanks for your continued support. What I have now realized by looking a lot of pictures on the web of various 2012 and 13 Corollas is that there are 2 different styles of steering wheels, hence why you were suggesting about needing junk yard find. I did not pick up on this difference before. I will call these different style steering wheels “Spiked” and “Smooth” to reflect the Steering Wheel Control (SWC) type. See pics.

I have found zero pics of the Spiked type with dual SWCs. Which now makes me wonder why do they sell the Spiked style dual SWC?

My hope is that I can use the Spiked version I purchased (with a correct clockspring) as I it does not look like the airbag and perhaps other components fm the LE can be used on a S style steering wheel.

And info on the parts compatibility between the two? Or other insights you may have is greatly appreciated.

Supreme,
Yes in the US. The folks at Clockspring Experts have the different style clocksprings and I currently assume I need to get an “S” version > at least that had dual controls. Thanks for the tip on the 2013’s LE having a dual control but I still cannot find one for sale on the web. I did see one with the large screen OEM radio with BT but still only a LH (spiked) control. Thus, I am concerned that a clockspring for a S, while accepting the dual SWCs will not fit into the LE arrangement.

And roger on the adaptor: I plan on using a Crux SWRTY-61N. I have written them asking what functions it supports as the OEM version of the dual SWCs has a total of 7 functions vs. the 8 which is what I bought. Are there other programable adaptors out there you are aware of? I would like to look at those as well.

 

My understanding is that the right side is a cover plate and is removable. But you will still need the correct clockspring assembly for the Bluetooth to function. You can confirm this by removing the airbag while at the junkyard before doing the work on your car.

I have a spare steering wheel that I got from the junkyard a while back for my Mazda. Lucky for me, the layout is the same for the one I bought. The controls are able to be swapped out on mine. It’s just a matter of tackling the swap.

Another thing to consider, some of the 2012-13 Corolla’s has the flat bottom steering wheel as a model change. Just FYI in case you opted for it.

 

The differences between the regular sport steering wheel and the flat bottom steering wheel for 2011-2013 was something I was wondering about as well. The buttons themselves and the silver trim aren't interchangeable but I believe the clock spring and the boards for the button should be compatible between the two. Can't 100% confirm though

 

The wiring shouldn’t have changed unless they changed say putting the cruise control switch on one side. Clock spring is the most important part to get it to function.

This brings up something I was wondering. If the connector with the Bluetooth function and the non Bluetooth would have the same pin out.

 

Gents,

I guess I’ll find out. I will be tackling this in the coming weeks so may be a bit. Spring is about to be upon us and I get really busy. However, I did order up a “Smooth” set of SWCs as a 'just in case' I need to change up the steering wheel. I will post what I discover.

However, I do find it curious that with the most sold car in the world that I cannot find someone who has tackled this before me. We are talking a car that is now 12 years old! Oh well….

 

Quick and perhaps a disturbing update. I have been emailing tech support at Crux regarding their SWRTY-61N device to allow SWCs to be used with an aftermarket radio. The tech is suggesting that the device will NOT allow a voice activation button to trigger the voice recognition (VR) on the new AM radio. Quote The outputted data from those buttons won’t let the radio activate the VR. Unquote. I have gone back one more time as there are 2012s Corollas with an OEM installed voice activation button and asked ‘are you sure?’ since that is contrary to their advertisement.

It seems others have had some success with the Crux but now I am thinking I should go with the more expensive iDatalink Maestro RR Interface Module.

What experience does the forum have with these competing unit?

 

And what the heck is a Corolla ZRE15?

The chassis code for the international wide-body varient of the 10th-generation Corolla and Auris is E15x (the 'x' is replaced by a number depending on which model/spec etc you have), on the New MC platform. Japan ran the narrow-body E14x chassis on the MC platform, and the US/Canada a wide-body version of the E14x. The ZR bit is just referring to models which came out with that engine (such as 2ZRFE) but shouldn't play a part in the steering wheel controls etc.

 

I just looked it up. According to this, SWR-A | Steering Wheel Control Retention Interface for Vehicles with Analog SWC | CRUX Interfacing Solutions the VR is retained. Is this the unit you purchased? It doesn’t mention about factory headunits being compatible.

 

This lists 2012 corolla and up as keeping the VR function. Controlled with dip switches.

I have not bought it yet as i am trying to tease all this out first. And roger on their claim it does work and the dip switches. Was hoping to get some insight on the 4th function of the RH SWC (Display) that is not part of the OEM set up, but his suggestion is it does not work.

Just in:

Here is tech support answer to my question posed above:
Quote: No, that button is routed to the factory mic. It would still activate the factory mic but nothing will receive the input. Unquote.
I do not think he knows what he is talking about…..

 

Personally, I would talk with crutchfield. Maestro or datalink will be a better product? I wouldn’t know since mine are factory.

 

Aces,
Thanks, and I do use / have used Crutchfield. Those guys are great and they are the ones that recommended the Crux. But since I was doing an unusual mod (adding the RH SWC) needed to go to Crux.

And I was sure hopeful that someone out there in Toyota Nation that has done this (adding a second SWC).

Bueller? Bueller?
