Hey guys how do you upgrade its firmware and where can I find the firmware as on www.onda.cn I couldn't find it ? And which is the best the VX858LE or VX858LE Honey or VX878 (apart from the screen size)? And if for example I buy a 1GB model then I can upgrade it to a maximum of 5 GB? What is the navigation icon? Last question  can you change it's language from Chinese to English?? Thanks very much for your help. I appreciate it very much!
 
 
 
Hope it is in the right section
