You can cancel the subscription, but they charge a $75 activation fee. For most of us XM's $29.95/month service would be ok. It isn't as comprehensive as the $50/month server but it still gives you TFRs, NEXRAD radar, forecasts, TAFS, and METARS.
I put a webpage together of "screen shots" after we got our 396 up and running last August (I don't have one with the TIS/Traffic information on-screen though):
