I made a call on my Sony P990i today via my retrofitted Gen 12 ULF. The phone wouldn't disconnect after making the call.

The red phone symbol won't go out.
The green bar is lit
I have tried turning the phone off.
The info page says connected for 822 mins and still counting.
The stereo won't function. It just stays silent.

This happened before and I had to disconnect the battery. Does anyone know whats going on. The retrofit has been fine for 6 months.

This is a Euro spec car (UK 2002 M3)

Help please.!
