There are some instructions available on KIATechInfo that you'd have to piece together from different sections. Basically you'll have to remove rear part of the headliner to be able to get to the connectors and the nut that holds the base of the antenna. Disconnect the quick connectors from the power cable and the antenna feeder cable. Once both are disconnected, just remove the nut that holds the base to the vehicle and you're done. Installation is just the opposite.
