Might be worth plugging one in and see what happens. I think that's pretty common for iPods and video cameras.
Your MyLink 2.0 is different from the one in Cruze.I own a 2013 Chevy Spark with the MyLink system which is the as other Chevy cars. I found a way to override the video disable when the car is moving. Open the MyLink cover and find a green wire that's part of the main wire harness. I cut that wire an connected to longer wires from those green wires to a toggle switch that allows me to open and close the circuit. When you open the circuit (cut the feed) you can view MP4 and MPG videos while moving but you loose the outside temperature reading. If you turn off your car, it will also drain your battery. When you close the circuit and restart your engine, you'll regain the outside temperature reading and everything will work like it did when you got the car.
If you want to see a map, you can download map images in JPG formats to a USB drive (in JPG format) that you can open and view them on your MyLink screen. I have a "map" folder on my USB with over a dozen map images that I periodically refer to when I am not sure of where I am on the road.
