The XM radio on my Z2 is stuck with the "updating" message. Oddly enough I'm receiving traffic data OK but the audio portion is only giving me channel 1 - like it did when new. I've tried the following:

- Sent refresh signal from XM. Didn't work.

- Hit reset on the unit. Didn't work.

I'm on firmware version 2.0005.

Any ideas?

I was able to fix this by unplugging the XM component, cycling the power on the main unit, plugging the XM component back in, then sending a refresh from XM. Works fine now.
