I got this used from a friend and I installed it in my 94 BMW 740i. Problem is when I turn it on the display reads "Reset" for a few seconds then shuts off. Also the magazine will not eject. One time I actually got the magazine ejected then when I reinserted it and turned it on it tried to load a disc but then I got the reset error again. It looks as if the disc is in the play position and is stuck. Magazine still will not eject. Is this problem fixable? If not then is the CDX-530RF still available for purchase (seing as how this is already wired through my car)? What can I do?
