It could even be something like a crappy solder joint, I've certainly opened my cable to resolder it because of intermittent connection issues.
Bottom line, it seems crazy, but you've only got $20 to lose trying a new cable, and it's probably the most likely culprit.

I am having even worse luck with my iPhones. I just acquired a CPO 2011 328xi without iDrive, and the dealer gave me a Y-cable to integrate my iPhone. Here are the applicable codes from entering my VIN into bmwvin.com:
S639A - Preparation f mobile phone cpl. USA/CDN
S6FLA - USB/Audio interface
When I plug the Y-cable into the center console, and either an iPhone 4 or an iPhone 5/5S with Lightning-to-30-pin adapter into the other end of the Y-cable, I can't find any way to access the music on the device. The Audio menu just shows "Tuner", "CD", "Aux" and "USB". Selecting "Aux" switches to Aux but when I play a track on the iPhone, it just comes out of the iPhone speaker. Selecting "USB" displays the message "Insert USB".
I have tried this with:
- iPhone 5S (iOS7) -> Lightning-30pin adapter -> Y-cable -> USB & AUX ports
- iPhone 5S (iOS7) -> Lightning cable -> USB port
- iPhone 5 (iOS7) -> Lightning-30pin adapter -> Y-cable -> USB & AUX ports
- iPhone 5 (iOS7) -> Lightning cable -> USB port
- iPhone 4S (iOS6) -> Y-cable -> USB & AUX ports
- iPhone 4S (iOS6) -> 30-pin adapter -> USB port
I didn't expect the 2nd, 4th and 6th efforts to work, since I believe I need the Y-cable to get audio, but I tried them anyway for completeness.
I also tried all of these with and without Bluetooth enabled.
Anyone have any tips or pointers, or what am I missing?
Thanks!
