Can't seem to find a solid answer to these questions. My head unit (IVA-W200) got jacked while I was at the gym and the insurance will replace and upgrade it. The current set up has an optical cable running to an H701 processor. I know the W205 will control the H701, but will the W203 and the W505 control it, or will they only work with the new H100? I'd love to get the W505 if it will fit into the current set up. Thanks for your help with this.
