Well, i don't pretend to be any sort of android expert and barely know my way around an android phone and have never even seen one of those Asian 3590s for real to be honest. But I would be surprised if those devices are anything but very good and maybe they are even excellent. There are also the 3595 which adds digital TV reception and the 3595R boxed with a driving recorder. Have a look at the Garmin Asian websites for details and there is at least one thread here dedicated to the 3595R. Maybe ask some questions in there if you need more info: [Only registered and activated users can see links. ].
