Troubleshooting
The troubleshooting information listed below is for general reference. 
Consult the User Guide for your SiriusXM-Ready headunit for specific 
operating instructions and advisory messages that may be displayed. Your 
headunit may display slightly different messages. 
If you see this on the 
screen:
Try this:
No Signal (NoSignal) •Make sure that the vehicle is outdoors with a clear 
view of the southern sky.
•Make sure the Magnetic Mount Antenna is mounted 
outside of the vehicle.
•Move your antenna away from any obstructed area. For 
example, if you are parked in an underground garage, 
you should receive a signal after leaving the garage.
Check Antenna (Chek 
Antenna, CHK Antena, 
Chek Ant)
•Make sure that the Magnetic Mount Antenna cable is firmly 
and securely plugged into the SXV300 Vehicle Tuner. 
•Make sure the antenna cable is not bent or broken.
•Turn the headunit off, then on, to reset this message. 
If the message persists, most likely the antenna cable 
has been damaged. Replace the antenna.
Antenna Disconnected Check the antenna connection to make sure it is fully 
plugged into the SXV300 Vehicle Tuner.
Antenna Cable Shorted Replace the antenna.
Check Tuner (Chek Tuner, 
Chk Tunr)
Check the SXV300 Vehicle Tuner connection to the 
headunit and make sure it is plugged all the way in.
