Review on Apple MD824ZM/A Lightning to 30-Pin Adapter (0.2M): Enhanced Compatibility for Apple Devices by Ryan Will

This genuine Apple product is the only one I've found that works with audio. I used this to connect an iPhone 12 Pro to my Alpine head unit which uses the legacy 30 pin connection. This works great, but it should probably cost maybe $10, $20 at most. I'm trying not to think about paying $50 for this thing.
