brand new, in box. I already have a headset, so this is not needed. Asking $45 shipped or $40 picked up.

Add hands-free calling to your Eclipse AVN6620 receiver. This handy interface lets you answer incoming calls and place outgoing calls with Bluetooth compatible phones — all without fumbling around for your cell phone. You'll be on your way to safer driving, conducting conversations with both hands on the wheel and your eyes on the road.

To get started, plug the adapter into the AVN6620, then mount the included microphone and push-to-talk switch. Once you set up the system, your Eclipse mutes automatically with each call, and you'll hear the caller through your car's speakers.

 

This should work on the AVN52D also since they are basically the same unit. One is retail and one is for shops. I have the AVN52D and this adapter also. Price is right on also.....bump
