Hi. Have 1998 with aftermarket (Alpine) double DIN touchscreen head unit and aftermarket speakers. Does anyone know if it is possible to swap for a later model LC steering wheel with the multi-media buttons (Volume and "Advance" on left / Cruise Control on the right) and the smaller airbag cover - but wire (at least) the left side (volume and "advance") buttons on the steering to function with the after-market head unit?
