I'm looking to buy a cable to connect my iPhone or iPod to the car. It needs a lightning connection but I noticed that when I'm looking online for cables there are 2 options. 1 says it's an integrated cable with just the lightning connection. The other has the Lightning connection and also a 3.5mm jack. What are the pros and cons of each? I've got an iPhone cable connected which is for an iPhone 3/4 and seen there's an adaptor on the apple website, would this work? Would I lose any features doing it this way?
