XMTM satellite radio reception (if equipped) XMTM is a continental U.S. based satellite radio service that offers more than 160 coast to coast channels, including music, news, sports, talk and children's programming. XMTM provides digital quality audio and text information, including song title and artist name. A service fee is required to receive the XMTM service. For more information, contact XMTM at www.xmradio.com or call 1-800-XMRADIO (1-800-967-2346) for U.S., www.xmradio.ca or 1-877-GET-XMSR (1877-438-9677) for Canada. The XMTM satellite radio receiver that is fitted to your vehicle receives the necessary signals from two specially designated satellites that are in a geostationary orbit over the equator. One satellite covers the east coast and the other covers the west coast. Both of them direct their signals north. These signals are then relayed throughout the USA by a network of ground repeater stations. The satellite radio signals are transmitted as "line of sight" signals. Line of sight signals can be blocked by objects such as buildings, but the network of repeater stations allows signal coverage within urban areas such as cities. 1) 2) Unscrew Remove The roof antenna is installed in the center at the rear part of the roof. It is possible to remove the antenna rod by unscrewing it from its base. & FM reception Although FM is normally static free, reception can be affected by the surrounding area, atmospheric conditions, station strength and transmitter distance. Buildings or other obstructions may cause momentary static, flutter or station interference. If reception continues to be unsatisfactory, switch to a stronger station.
