I bought a car in January, 2016 and was given a 3 months' free subscription. They called me when that was getting ready to expire and offered me several different options, the best being 6 months of All Access for $56.94 including all fees. Since then, I have called and renewed every 6 months and have always paid that same amount for All Access, as it worked out the best of all the options they offered.
My plan was about to auto-renew tomorrow (5/1) at $25/month, so I called to request the same rate. The first representative said she couldn't do that, but implied that if I was going to cancel, she would transfer me to another representative who could 'talk' to me about it. I ran through the same thing with the second agent, who said the best she could do was $64.31 with all fees, but spoke to a supervisor who gave an additional credit down to $54 for everything.
Be polite, but insistent, and they will eventually give you a much better rate than they initially offer.
