Eventually I was able to find a couple of link sources to the FX3.1. However, spent massive time reading up on all the pages. Avic-f700bt owner here btw, At the step where I reach the blue screen and input the service code, I select update wince, update from SD card but the screen goes black after a few seconds, it just wont stay on that blue screen long..... Not sure what Im doing wrong. I still went ahead and tried deleting contents from Flash drive, copied all the contents from the FX3.1 flash drive folder onto it, Its caught in a splash screen booting loop. I even tried to revert to the 2.
