Hi travelling with my 3 yr old on the train in a few days, but normally travel by car so want to get a dvd player that can use on the car headrest too. Husband saw one in aldi but I don't know how this would attach to headrest, I've seen one in halfords that come with a car mounting kit, but it is a tablet type and only has a picture frame type stand, which might be a disaster on the train. My budget is fairly limited I don't want to spend much over 80 and definitely under 100 and that's even stretching it. The tablet type has a usb port which seems like a great idea. Does anyone have any advice? thanks very much.
