Bigfish 3.5MM AUX INPUT INTERFACE ADAPTOR CABLE KCE-237B Replace KCE-433IV FOR IPOD MP3 ALPINE IDA-X301 IDA-X301RR IDA-X303 IDA-X305 IDA-X305S CDE 101R RM 102RI 103BT 104BTI W203R

My Alpine ida-x305s radio has received new life! This cord allowed me to input my IPhone 4 music into the car speakers at a fraction of the bluetooth unit's price. I picked up my VERY PROMPTLY SHIPPED cord at the post office and installed it right there in the parking lot! So easy, so useful. I was waiting for a problem...other than a shirt length (it could use another 12" of length)there was nothing!!!! A must buy!

Amazon really should have companies update their titles for products because this is one that doesn't provide any details for your specific head unit other than a list.However, this cable WILL NOT work with the Alpine IDA-X305S. This cable is meant for a completely different head unit made by Alpine.

I needed a way to connect my cell phone to my car audio which doesn't support Bluetooth audio. Now I can and I'm able to use other cell phone options through car audio that I wasn't able to do before. Great but.

Didnt work on my model alpine bogus buy

perfect
