Hi,

I have got a Becker BE 7920 Indianapolis on my bench, was short circuit and blowing fuses, found a SMD diode S/C, I cannot identify this part or find a schematic, radio powers up without it, so not sure if it's for overvoltage protection, what it drives or for Navi (Can't test as I have no CD)

The only identifier is EPP 47, I am also looking for a Navigation CD for UK? I cannot find one anywhere to download.

Thanks,
Dale
