For audio, connect your i-device to the rpod stereo via bluetooth. Now you have good sound too. 

You can either stream or watch recorded movies. 

The next step if you camp without hookups is to swap the TV out for a dual voltage one and add a 12V cigarette lighter outlet behind the TV. Get one that also has a usb charge port and use that and the extra lightning port on the a/v adapter to keep the i device charged.

Step 3 if you want to stream in weak signal areas is to get a weboost cell signal booster and mount that near the tv so you can put the iphone in it. Then get a Wilson cellular directional antenna, 50 ft of low impedance coax, and an extension pole like the ones used for window washing. Bolt the antenna to the pole and clamp the antenna to the rpod when you set up camp. Run the cable to the weboost and raise the antenna, slowly rotating it to max out the cell signal. Works great as long as there is a signal to boost, but it can't boost something that's not there. You will need an unlimited cellular data plan of course. 

Now you have streaming and recorded video and stereo audio just like at home while camping. Great for those rainy days. You can also use it to stream music from Spotify or other streaming service via bluetooth to the outside speakers, just don't annoy your neighbors by cranking things up too loud.
