Ok so I'm really new to dash cam's but not to loading firmware onto electronic devices. With that being said has anybody had trouble updating firmware on Lukas Lk-7900 Ara with OBD II to version 0A31? No matter how many times I try the firmware says it is updating but it will never finish. It locks up and then I have to go back to v.AC31. I just purchased the OBD sensor two days ago and it won't show up on the play back in the viewer. BTW I am using the correct viewer that works with the OBD sensor. Thanks in advance.
