I also tested driving many occasions ( my wife driving)and it did work fine on my phone.
I would get the support and pay for the unlimited one....
For the first year if you will install different equip is great to have extra help...
You can attach all kind of stuff and control from anywhere.
Helps to have at home a good internet but do not have to be the fastest one.
We can create at the support soft to control new equip not listed and you can get help with everything else!
This slingbox is the best!
I couldn't agree more that's it's a great product. I've never set up the box and downloaded the software on my devices. My laptop and phone are located with me overseas and the new 350 box is in the US.....will I be able to set up my slingbox for the very first time without my laptop/phone and 350 box all in the same spot?
I hope this helps clarify my issue.
