I gave it a try several times but all I get is the first android screen which states it has 65% charge then it goes off then it goes back to the same screen as before round and round over and over and never stopes unless I press the power button when the screen is blank I think I have pressed every combination of buttons and held every combination for a short time 10 seconds and a long time 2 minutes but it does not start, I also tried every combination both plugged in and not plugged in it is a pain in the arse it's not as if it gets to much work I only use it for maps in my car I just ordered a samsung galaxy tab 7 which I will have to put up with as I have a couple of others but I doubt they would be any good as I have a Asus transformer v1 along with the separate keyboard which also has a extra battery in it which was a great way of doubling up the battery power and I have one one of the samsung galaxy note Pro which I think would be a little large sat in the car as it has a 12 inch screen.
