The cable which connects to the iPod is easily replaceable, and I had to do this at some point (when the iPhone 5 came out? I forget) because the newer phone wouldn't charge. The fix was a different cable, it has the apple dock connector on one end, and a RJ-style jack (like a phone or network cable jack) on the other. The way my iPod kit was installed, I needed to remove the passenger footwell cover (above a front passenger's feet, like 3 or 4 screws), and then the device was visible. The cable runs from the device up and through a hole in the side of the glove compartment. Easy to replace.
