Check my signature "how to" it should answer a lot of your questions. Not sure on your XM.trophybass said:Hi, i'm new to the Armada world.I did search but this subject has so many replies that i'm starting to get lost. I have an '04 SE 4x4, It has the roof console for the monitor but it must not have been purchased with one originally. What i would like to do is install a player into the armrest console and a monitor in into the factory location. I would like to use wireless headphones but i am having trouble understanding what i need to get (monitor, player and phones) and where to get power from for both the player and the monitor. SHOULD there be a factory harness inn the headliner and near the armrest console? Also i want to install the XM system from my old headunit into my factory armada headunit. I have the receiver and the antenna (and i guess i now need to get a controller) but my controls were in the HU from my old truck. How can i hook it to the factory system? or is this possible? Sorry for the newbie questions. Thanks
