Nice thread but I am lost.
I have the Z120BT and downloaded the torrent, copied dat and other file mentioned on a 8GB SD Card, turn on the car and inserted the sd card but nothing popped up prompting me for an update, didnt even see the card. I formated the card to fat32.
Do I need to be in test mode?
I am sure this has been mentioned but I see instructions for the other models.
