I have the Alpine 9833. What do I need in terms of hardware to listen to XM Statelite? Is it just the antenae and the tuner?

 

All you need is receiver box, antenna, adaptor cables, and subscription for service. These are all plug and play componants the hardest part is finding a good location for the tuner and the antenna.....With XM you will not listen to regular radio again!
Later
