Bought a 2nd Tivo for a relative in Omaha, NE. New unit was a Tivo Vox Bolt. The new UI is quite unpleasant...but that's a different issue. Sooooooo, I trot off to a Cox Solutions Center and pickup a Tuning Adapter and cable card. No wiring diagram or setup instructions are included with the TA. I hookup the TA based on the connector labels on the unit (mistake) and install the cable card. I call Cox tech support for cable card activation and the fun begins. 1st call: no joy (activation fails), only channel 1 is authorized for the relative's account. Tivo does not "see" the TA. 2nd call: New tech employee politely establishes that I'm an idiot and that the tuning adapter is incorrectly hooked up. With the tech's help, I correctly wire up the TA and Tivo now knows that the TA is present. Cablecard activation is attempted again. No joy. 3rd call (made after reading about activation issues online and possible solutions): New tech support employee tries activation again. No joy. 4th call: New Support tech says that he's worked thru activation issues for a lot of customers and he gives it a go. No joy. I've spent 3-4 hours on the phone at this point. The tech and I start to think I have a bad cable card. I request a truck roll and he agrees. I request that the responding tech come with more than one spare cable card. Two days later, on-site Cox tech employee arrives. This is the third Tivo he's seen in three years of employment. He arrives with one spare cable card. I show the tech the Tivo cablecard diagnostic menus and he calls the Cox cable card support dept and they troubleshoot the problem. No joy. Now we really think it's a bad cable card. He calls for an additional tech to come to the house just in case we need to go thru a card swap party (the additional tech also has one cable card in his possession). The first on-site tech and I chat a lot in between troubleshooting phone calls to Cox and I can tell that activating Tivo's is not a fun experience for Cox employees. The 2nd on-site tech arrives and before we start swapping cards, the first tech presciently escalates the activation problem to 2nd Tier cable card support at Cox. Tier 2 support tells the tech, "We know what the problem is. The 'hit' signals (for activation) that are being sent to the cable card are not 'authorized' on our end, so they aren't touching the customer's card." Tier 2 fixes the authorization issue, activates the cable card, and now Tivo works. Soooooo, it took 4 phone calls (one is my fault) and a truck roll to activate a cable card in Omaha. Yee haw. Moral of the story, if activation doesn't work and your TA is hooked up correctly, immediately request Cox Tier 2 support. Hope this helps someone else dealing with Cox.
