iBus/dead sat nav screen issue

[deniz]

Hi all,

I recently tried using the ibus interface on my e46 m3, however I noticed a small spark when it touched the casing for the satnav/cd player (I guess the pins were in the wrong part). Following this, the ibus won't communicate with the laptop at all and worse of all, my sat nav screen/radio/cd player are all dead. Nothing comes on the screen when I turn the car on.

I tried taking the relevant fuses out and putting them back in (7 & 41) to no avail. Anyone else had a similar experience?

Thanks for any help.
