Oh jeez that’s not a bad deal at all, and that’s almost what I was doing. I would just let the subscription/deal lapse and they would call and ask why I didn’t renew. Told them I’m not paying $15 a month and than they offer the $60 for a year or 2 years.
At the time they didn’t even have dedicated car units, you had to have one of their portable units, and an am/fm adapter or tape adapter.
