Stock Steering Wheel with Audio Controls Connected to After Market Headunit?

Hi all,

I own a 2005 Swift Vxi and was wondering if I could firstly fit a steering wheel with audio controls which is available in the latest Swifts/Swift Dziers. If yes, any idea as to what would be the cost of the same?

Also, since these steering wheels with audio controls are meant to control the stock headunits which come with the car, is it possible to have them connected & be fully functional with an after market headunit like an Alpine 9887?

Mods : Found a similar thread but all posts were off topic – The title said steering wheel with audio controls but steering wheel remotes were being discussed.
