I,m not sure if you can help me, but I recently bought a magden form a previous owner and he failed to mention that he had the red wire as the ground. Of course this resulted in the device failing and now i am very bummed. By any chance, have you registered your magden on the Magden website which allows access to their software update? I am trying to get the software to reinstall it on the hard drive. If so, could you please let me know.
