I have that one, are you sure its Android because mine is WinCE.
My previous one another chonky make would crash all the time like yours, it just could not multitask yet the A-sure one which was a bargain at £80 is completely stable.
It has a couple of niggles that I cant resolve like the door handing, that I programmed out on the other unit but cant find an option to do it on the A-sure, there is a further factory programming menu only accessible by the factory code (try 3368) where the function should be found but they are all in incomprehensible Chinglish and none I tried would change it.
Instead of being able to choose between 4 backlight colours for the buttons mine only has Blue and White, the latter just being a dimmer Blue.
Not even tried the Bluetooth on this one, the last one drove me mad because it wanted me to repair the phone every time I switched on the ignition.
I hit lucky this time, all the functions I want to use, radio, CD, CD's copied to the memory card, Satnav, reversing camera etc all work and will work together without it crashing, for the money its more than I expected, my expectations were revised to reality after the experience with the first unit, a Tingtonglinglong something or other.
