What about steering mounted music control? Can I manually add?

Although you can do the changes, but from outside we don't suggest any modifications. Because tampering the steering wheel of the car would lead to mishaps some times. Also while installing the controls on the steering will hamper the wire connections and that too can also affect other electrical parts of the car. Moreover, we would suggest you to have a discussion with the service centre as they will be the better people to guide you in this - Service Center.

In order to add music control to the steering whole steering assembly needs to be changed and for the confirmation, we'd suggest you walk into the nearest authorized service centre as they will be the better person to assist you.
