Please update if you are able to downgrade firmware on the Dasaita.How is your HU now? Does the downgrade firmware version help?
My current MCU and firmware are auto-launching both Z-Link and default navigation on boot up.
I tried to install an older firmware posted in this thread but, the unit stops, claims it cannot be downgraded, followed by exiting to bootloader.
I have contacted Dasaita many, many, many times over the past 2 weeks with no response.
They finally responded today with a link to an MCU image file.
It was the same image file I currently have. I loaded it anyway.
Still has the same problem.
