I called today and tried to use the ZWINBACK coupon and it worked....$77.00 / yr with no activation. No issues there. Then, I tried to deal for 3 months free NavTraffic and was put on hold 3 times.....then, I got disconnected.. I'm going to call back tomorrow, throw a major hissie fit and try for 6months free NavTraffic.....I'll keep you updated!!!!
I used zwinbackmyp1 today and got $77 for the first year, $0 activation, and 3 month free trial for nav traffic.
I was going to try the same thing except try and haggle for 6months free NavTraffic; however, I am reaping the benefits of a refurbished XM module (receiving free XM) so I am not going for the NavTraffic until the gig is up....Thanks for the update though!
I tried ZWINBACKMYP1 today and was put on hold several times. I got $77 a year w/no activiation fee but couldn't get the 3-months of XM Navtraffic 
I called and used the promotion code zwinback and the other codes mention above and they wouldnt take them. I hung up and called right back. I didnt mention any codes and I got Nav traffic and XM radio for $124.88 for a year.
LOL u musta spoken to an asshole rep or something, cuz i used the zwinback today and got 77 a year no activation and nav traffic free for first 3 months and 3.99 a month there after! oh yeah , no argument what so ever. i just told rep the code, she put me on hold for about 30 seconds and then it was all good
Does this work for new subscriptions? Do I just tell the rep I have a promotional code and give them ZWINBACK and it should work?
Thanks.
Will this code work for online activation?
I just called and she said that code was coming up invlaid in her system.
Samething happen to me. You will need to hang up with her and call back. Once I did this I received the promotion. Well actually when I called back i didnt give her the code # but I told her that I had a code that was suppose to give me a yr of XM for $77 and I just added NAVtraffic. all in all it came up to 124.88 for both for the year.
The trick is to keep trying different CSRs until you get what you want.
Success!
The "ZWINBACK" code is still working--just activated today.......just make sure that you tell them you got the code from a letter you received in the mail.
Just activated my account today. I got 3 months free of the radio service and navtraffic along with the $77/year for the radio service, so I don't owe them any money until March 10, 2008. Sweet deal, I must say. I just told them I got a new car, and I had the coupon code and that I wanted 3 months free of the navtraffic. I didn't even tell them the actual coupon code.
Will this work if you already have a subsciption?
