Completed the hard drive upgrade on my Series 2 TIVO unit. The unit boots up and when I try to go through Guided Setup, I enter the local zip code. The Guided Setup completes and says there are no cable providers in that zip code. I called Comcast and they said to use the zip code of the local retail store that services the area. I tried that and got the same message. I cannot even exit Guided Setup to Live TV. Ideas?
