Hi everyone bought my 1st seat, 16 plate 110 fr, only thing is it has the small screen touch screen in it, could anyone tell me if I install a aftermarket head unit would the steering wheel controls still work or is it a case of having to use a better spec OEM head unit? Also how do you uninstall the original head unit? If I did fit a upgraded OEM headunit which one is the top one to get and would I need to change the Arial for the dab side of things, thanks very much for any help I may receive
