Yeah, you gotta wonder. It makes you think right now the game between Sirrius and XM is who can get the most subscribers regardless of what it costs the company. I don't have a clue who/what the code was originally for, but I got absolutely no questions asked when I used it.
We just bought a 2007 Honda Odyssey with XM free for 3 months. I really like XM but don't want to pay nearly $150.00 a year for the service. I got this code "ZWINBACK MYP1" off a car forum and called the XM toll-free number. I told them I wanted to subscribe and that I had a $77/yr promo...
