I haven't run across that, checklist
1) the antenna with the tuning coil should be on the left side of the bike as you are sitting on it.
2) look at the black box under the trunk, open it ( two bands ) and check to see that the antenna ( It's a motorola plug like your antenna on your car) is plugged in, it should run out the left side to the antenna.
3) power chords are hooked up.
If it's a no go then check for power at the unit or the fuse.
4) is your headset & mic plugged in, the cb won't work without a headset.
5) connections, open make sure the pins are all clean ( not green) put dielectric grease on the connectors.
