Hi,

I just renewed my expiring 3 month XM trial on my '07 Cadillac SRX using the same ZWINBACK code. The lady asked me where I learned about this and I said on a GM website. She checked and said okay and then we charged $77 to my credit card. They also have a special deal on a XM radio for I think $19.99 that works on any radio, car, boat, etc. The monthly charge is $6.99 per additional user. You can add up to 4 additional users which can be family or friends or your own vehicles.

I thought you should know...

THX,
Denny
