Has anyone used Zenec Z-E3215? I have a problem with the update, I put it on a pendrive, connect it to a USB hub, go to the settings and go to the update, but when it reaches 100% it stops and nothing happens. The main problem is playing music via Bluetooth,
because after connecting to the phone and turning on music on it, it immediately kicks me out and disconnects me from the Bluetooth on radio. I thought the update would help, but I can't do it.
Is there any way to get directly to the operating system so I can have a look around? I know that there is Windows CE 5 because once I had an error that constantly displayed a Windows error and I needed to upload the update to the SD card and insert it in place of the current SD card with navigation,
which caused an update window to appear when you turned on the radio, unfortunately this time it doesn't work, after turning on the radio it goes straight to the home page. Alternatively, what can I buy in its place?
