If the cable on your adjustable charging holder has broken this kit will allow you to easily repair it. Simply remove the plastic block holding the cable from your old holder and attach the new one. This kit comes with a new block to hold the cable, screws to attach the block, and an MFI certified Lightning to USB-A cable pre-installed in the block. Connect the USB end to your car charger adapter (sold separately) for power or directly to your car's USB port for CarPlay (compatible vehicle/radio required)
