Hello,
Running a DUDU7 8G-128G-360IC for a couple of weeks now and was finishing install today (Had to change antenna adapter, etc.) and when complete, USB stopped reading devices (DAB+ box disappeared, ADAS 2K stopped being recognised).
I reseated all cables, checked all connections and all appears sound (ADAS 2K shows red power light). Plugged in phone and drawing charge power but again, no devices seen. Opened DAB-Z and it kept closing, opened DABDream and it couldnt connect to the DAB adapter.
Done a factory reset to make sure it was not some sort of software bug, but again, no joy. Noticed when trying to reinstall ADAS 2K that the USB disk does not show. To make sure it wasnt the USB devices, I plugged them into my phone and ADAS was recognised instantly and I could see the file system. This appears to be a hardware fault of the unit!
This looks like the same fault in https://forum.dudu-auto.com/d/726-dudu7-no-usb - its also the same model of head unit. I am running the latest firmware (No change since it was working and not working). The whole time I was working on HU, battery -ve was disconnected from the vehicle. Only change was added a 8mm Din to 8mm Din/SMA sliptter so as I could use roof antenna rather than window antenna.
Any more info needed, please message.
Thanks in advance.
