prbarnard and others,
Help me better understand, I'm trying to recreate your configuration with my phone and it's causing me great frustration.
iDA-X305 -> original usb cable -> original usb-to-30pin -> authentic 30pin-to-lightning -> iphone 6 with ios8
I've also tried it with my ipad air and no luck.
It does work with an older ipad that has the 30pin plug.
Tried resetting the headunit and phone at least a few times with no luck.
Also tried removing the headunit and pluging in the apple 30pin cable and using the apple 30pin-to-ligning adapter with no luck.
It must have the alpine usb extension and original usb-to-30pin to work.
Pictures/video would help, also any specific configurations inside the headunit or other areas I might be overlooking?
