I've been offered a CD Changer for my car - a Sony CDX-757MX. The thing is,
I can't tell if I'd be able to attach it to my HU - a Sony WX-C570R.

The HU manual says it will accept:
CDX-805
CDX-715
CDX-T65
CDX-T62

Or source selector XA-C30

Does anyone know if I'd be able to use this changer, and if so whether I'd
need any special adapters?

Thanks.
