We travel every winter in our RV. For the past 3 years we have brought our Direct TV Tivo with us. We always have been able to find military RV parks with telephone hookups. But this year we decided to go to Florida. We are not going to be able to have a telephone hookup at any RV park where we will be staying. We have cell phones and also have Sprint PCS Wireless connection for the Internet. Can someone please help us with the best way for us to make the update phone calls. I read some posts that said you didn't have to make these phone calls but the thing keeps breaking into programming to tell us to make phone call soon. Please try to explain as simple as possible. LOL Thanks a bunch!
