Here's the deal: I installed an iPad mini in my car. Had it connected using the guts from an iPhone 5S dock from Apple. Plugged the lightning connector into the iPad and then that gave me a lightning female port and a line-out. Was working great. But I just swapped the iPad mini for my new Retina mini and it no longer works. Still charges but no audio. Seriously bummed! Any ideas guys? The sound quality was much better with line-out than the headphone jack so I want to keep it that way. Just can't understand why it worked on the iPad mini but won't work on the mini with Retina. Any ideas as to what would allow it to still charge using the iPhone 5S guts, but not work with the audio port on that board? Thanks in advance!!
