ALPINE # CHA-S624 Ai-NET 6 CD Shuttle Digital Optical Dual Bus . This unit is only compatible with Ai-NET head units. Worked when I put it in storage 2 years ago but no longer have the alpine headunit to test it with so selling it as working condition, however, if you receive it and it doesn’t work I’m more than happy to provide a full refund upon return as well as pay for return shipping.
