Hi everyone, looking for some assistance as can't seem to pinpoint exactly what I need. I'm looking at replacing my stereo for a Sony DSX‑B41D DAB and wanted to know what cables/connectors/harness/bits n bobs I'll need so I can keep the steering wheel controls, power on n off, display and non Bose half amped speakers running. Any help would be greatly appreciated.

Thanks
