2010 Elantra - Steering Wheel Radio Control Upgrade Options

[ajlempka]

As you can see, the male connector (MM01) is shared for the left side audio buttons (M57) and the right side cruise control buttons (M60), so the EXT wire should provide the y-splitter for that.
My only fear is that MM01's female connector, M02-R is not wired for pin 11 and 12 connecting to the radio's pin 16 and 17. I haven't yet had a chance to do this because I haven't taken apart the steering wheel/column (stupid plastic in the way!)
If you have no idea idea what i'm talking about, I've included the schematic diagram






Has anyone else attempted this project, if so any success?

On a side note, where did you get these diagrams from kish21? HMAservice's are too small way to difficult to read.

From HMA service, full screen mode aka "pop-up viewer".

Okay I got the parts from South Korea yesterday, and today I got to work. Project was successful!
First lets have a look at what I got:


Switches 96700 2H200-S4


and y-splitter extension cable 56190 2H200

Unfortunately, the switches were of the same kind as the one I ordered earlier through the dealership. They were silver color, but had a honeycomb texture.
Next thing I did was without removing the existing blank insert, I plugged in the new switches and extension cable to see if it works.
Fortunately it did! See below:





Next step was to remove the existing blank plastic, and this is where things got frustrating.
The proper way to do this is to first remove the steering wheel off the column completely in order to access the two screws to remove the blank. Unfortunately, a special tool made especially for removing steering wheels is needed to do this, and of course I don't have it. I tried trying to yank it off by removing the large nut in the center of the wheel, but damn the thing is solid. It was getting late at night and I was getting impatient to go hunting for another tool, so I went to plan B. This involved putting a phillips bit into a the small opening through the front of the wheel and very very very slowly removing the two screws. I used a needle-nose pliers to get enough torque to unscrew those screws:



The whole process was very long and frustrating as the gap was very small and the screw was very tightly held. It took me well over two hours and cut fingers to get those two damn screws off. Those metal are sharp, be careful! Anywho, the final result was this, getting that blank piece off:



Next I removed the existing extension cable for the cruise control, and installed the new y-splitter extension cable. One very important thing to note here, the cruise control side is missing one cable, the yellow one. Without this, the cruise control light wouldn't even turn on. Simple fix was I ran a cable from pin #3 of the MM01 connector to pin #8 on the M60 connector.



And here is the final result! Overall, it was a good project. If someone else is planning on doing this, do yourself a favor and definitely get the tool to remove the steering wheel. I spent at least 3 hours total just trying to remove and insert those switches.
Overall difficulty 10/10 the way I did it. Otherwise with the proper tool, i'd say 6/10.

Hey what was the price difference between the dealership and South Korea?

[Red Elantra GT]

Hey-I rented the tool to remove the steering wheel from a car a while ago. If you're thinking about any project that involves taking the steering wheel out, see if the parts shop near you rents tools.

[kish21]

Hey what was the price difference between the dealership and South Korea?

Ebay/SK was $57.
Dealership was $98.
Both include switches + wire.

Here is that tool to remove the steering wheel. This is the specific one for Hyundai/Kia. I don't know if you can rent it, but if you can, that would be great.



And here is quick instructions on how to proceed:

Great job!!!

Side note the honeycomb texture is the normal texture. It's the same type I have which is also on my floor console and such.
