hunter 408 Report post Posted March 21, 2018 Question for those that have retro fitted Multi function wheels to their cars, or have these steering wheels and have fitted after market head unit. Have you successfully been able to control volume on the after market unit with the buttons on the steering wheel? Quote Share this post Link to post Share on other sites
qube 3570 Report post Posted March 21, 2018 Some headunits have the control built in to work with the MF wheel, some dont. If not there is an additional little unit/controller to make it work with older headunits. If you go to any audio shop and ask them which model headunit will work with the MF wheel they should be able to help you. From memory I used a late model Sony in the past and it worked fine. 1 Quote Share this post Link to post Share on other sites
