I reserved SiriusXM at the time of booking since with my AAA discount it only costs $2.50 per day. No one at the exit booth said anything, and even after I called Hertz, it was never activated. Fortunately, at return time the agent took the charge off my account. Seems like Hertz has really turned satellite radio into a real scam.

A local HLE that I use on occasion will charge me for SiriusXM, and then issue a miscellaneous credit to offset the cost. That doesn't always happen, but will if I get the regular agent there and she recognizes me.
