Updating your Concertone receiver?
If you're replacing your Concertone RV multimedia receiver, you can simplify the job with this harness. It adapts the existing wiring harness that now plugs into your ZX500 or ZX600 receiver so it will connect to a new ZX690 or ZX800 receiver. Less wiring equals less time installing, and more time enjoying your system. Warranty: 60 days.
