I have an XTRONS td691gt. It had a fault where the bluetooth call audio was 100% volume no matter what the actual volume was set to (very loud). I contacted XTRONS and they sent me a firmware update. This turned out to be a mistake. :( I still have the audio problem, half of the radio functions no longer work (TA PTY AF) and the boot video is TOYOTA (it used to be XTRONS). I have tried to sort it out via the XTRONS help but they are not interested. To be clear, I'm not talking about the image logo (I can change that), it's the little video that plays on boot.
Anyway - All I want to do is change or remove that video. I'm resigned to the radio not having 100% of the functions back...
Is there any software around that I can use to access the files and change it? (It doesn't recognise anything connected to the USB).
