I'm trying to switch the XM radio to Sirius on a 2011 TSX with Technology Package. I have installed the Directed Electronics HONSC1 and SCC1 Tuner. When the XM tuner is disconnected, the voice command is disabled. The Sirius works and displays in the Nav screen. Once the XM tuner was reconnected, the voice command worked, but then XM took over the Nav screen. Also I can hear XM and Sirius and loss control of changing channels.(I have Sirius on it's own antenna) If the XM antenna is disconnected, the satellite radio does not work at all and a "No Antenna" message is displayed. Any idea on what I need to do to correct this??? Any help would be greatly appreciated.
