Yes you will need to change it. I could not get the multimedia buttons to work with OEM clock spring.
I see that you completed your project, did you finally manage to get cruise control working as well?
Anxiously waiting for the cruise control to work
Update March 2022. The aftermarket clockspring I purchased started creating problems. This was because I had to remove some of the plastic bits from the back of the clockspring to make it fit. It had started vibrating. I sourced another clockspring from eBay UK.
This one fit perfectly without having to make any adjustments. It had the required number of pins. However the pin configuration for this one was different so I had to redo the wiring harness and remap the pins. However it was a much faster job this time. Took about 90 mins.
Did cruise work?
Cruise work kia??
