First thing I did was turn the Nabi off to be sure I didn't hit any buttons while I was working.
After I made sure the device was off
I flipped the device over, removed the protective bumper, and found a small screwdriver.
Remove the six screws holding the grid square panel in place.
Select a material to use for the replacement rear cover. I chose a white lid from a RubberMaid container.
I then traced the grid square panel on the lid with an Xacto knife.
I made my first attempt with a cutting wheel on a Dremel, but it melted the plastic and made the edges too rough.
For the rest of my cutouts I just used the Xacto knife, tracing the lines over and over until it cut through.
I then placed the square grid panel on top of the cutout, marked the holes with a fine tip Sharpie, drilled the holes out with a small drill bit, and rounded out one side of the holes with a round tipped bit on my Dremel.
I then screwed the new rear panels on and decorated them for the kids with some paint markers. (Orange and Black were the only colors I had...)
Other users have used this method in the past to attach velcro straps to the back of their Nabis to use for children in the car.
After purchasing multiple car seat dvd players to entertain my children on long trips, but only last 3-6 months because of lousy materials. The last straw was the RCA DVD player from Target lasted 2 months; every bump and pothole the DVD would skip or jump or all together stop playing.
I decided to find a permanent fix since we are heading on a 5 hour trip. I then looked toward the Nabi and since I have two of them and two kids I tried a few attempts to mount the Nabi to the car seat but found a better solution that turned out to be free. And here are some pictures.
I took a DVD case and cut it to dimensions and drilled 6 holes to screw back in with two slots for velcro straps I removed from previous car seat dvd player. The pictures are self explanatory.
