Hi there - I'd like to add a MP3 compatible CD changer to a HU-803, but really don't want to pay Volvo dealer prices. I also know nothing about how they work, which isn't helping me pick one... The various sites I've tried that allow you to pick factory fitted equivalent models, but nothing is every listed as compatible with the HU-803, just the SC or CR models.

Has anyone on the list done this? Or could someone tell me which ones will work, or which 'interfaces' the HU-803 uses or requires?

Thanks

Julian
