So after contacting Joying for help with this and exchanging a lot of emails with them, they finally told me to swap the power and acc wire as some cars have them the other way around...Just wondering, how long are people's units taking to boot?
Since I updated to the latest firmware from joying's blog page my boot times are a lot longer. I used to have just one short boot logo to wait for but now I have two. Since the update there is the 'Google" boot animation as well as the other one and it seems to take ages.
I can't seem to change any options in the sleep settings either
After swapping the wires around the head unit boots instantly after turning the key! So sleep mode wasn't working for me before because the unit would do a full boot each time it turned the key.
Finally solved the problem, I hope this helps if anyone else has the problem I had
