Install a CableCARD™
If you have cable TV, your TiVo box needs a multi-stream CableCARD (M-Card) to receive cable channels, and to watch and record multiple channels at the same time.
You can pick up a CableCARD at your nearest cable service center, order one from your cable provider, or have a technician bring one to you (fees from your cable provider may apply).
Once you have your card, follow the instructions below to install and activate it.
