well arc tools didnt work but a man i know did.
I didnt want to mess about with it too much because i am unsure what to do and didn't want to brick it.
A guy on another forum (android one) offered to sort it and he really did.
Now it has google play plus a few other bits and bats plus using one of the free maps off play,the sat nav side is excellent.
so for £70 i have a tablet that will accept any sim card for the net,plus of course wireless, also google play as well as arnonva play store and a decent sat nav with an option so get tt truck on foe 39 euros.
good reult for me anyway.
