This has been covered a few spots in these threads, you have a E39.....the E39 does a diagnostic check of the lighting circuits with a low voltage signal.....that low voltage is triggering the dynavin's reverse function. The fix is to install a relay on the reverse wire to isolate the head unit from the low voltage signals.
