Losing all electric.. please help

[Leni479]

Please help. Just bought a 2005 z4. I'm not a mechanic but I try to fix my own cars and most of the time I can but I'm at a loss. First we lost the soft top motor. Chalked it up to water. But then radio unit including pop up display went. Now other issues like inside dash lights come on after driving a bit but no blinker inside at all but they do work outside. Take key out sometimes and it continues to beep. Now latches for soft top have quit. I'm gradually losing everything. Please try to steer me in right direction love this car would like to keep er straight. Thank you

Sounds like the k-bus is acting up. Google "troubleshooting the BMW k-bus."
