Did anyone throw Tag Reader books w/ tag pens or Vreader out there? sorry if this is redundant. Both of my kids *love* thiers and can spend a lot of time playing with them. You can use headphones with the Tag Reader and possibly with the Vreader to keep the noise down in the car. Admittedly, my kids (and I suspect your kids)are past the 'learning aspect' of these toys, but they are super fun none-the-less.
Also, we go to the salvation army store and pick up a stack of used books and bring them in the car to read... that is always a hit too.
For our last long car ride I bought a set of Tag books and each child got a new one ever few hours as the trip progressed. Good luck!
