I let my free new-Volt subscription to SiriusXM expire more than 3 years ago and don't miss it. But I'm thinking about taking advantage of the current $25 for 5 months offer, only because I'm going on a long road trip next month, and it's convenient to listen to BBC or whatever without having to change the station all the time -- but mainly I'm interested in getting realtime traffic updates on the car's navigation system. I know how to use Waze, how to stream NPR, podcasts, other content from my iPhone, etc.; I'm just thinking that having the Sirius connection could make the long road trip a little easier. (But: $25 easier?) Anybody want to comment on any of this? Thanks.
