Did you try to insert the USB and then push the little Reset button in the lef upper corner ? Update should start during bootup...Hello,
I have the same Junsun V1 Pro, but I have a problem updatting..
It doesn't do anything when I insert the USB stick in my car. I already tried with many other USB sticks FAT32 formatted of course.
The first time when I bought the Junsun, I managed to update without problem, but now even if I do the same way, I cant.
It is recognized by the Junsun, but the update pop up doesnt come up.
Edit : (I've just downloaded the latest firmware posted by hackras (thank you), I'm gonna try within 15mns, even though I have no hope)
Any clue ?
Btw. only one USB port is suitable for firmware update, did you use the correct one ?
