Does anyone know where the speaker is for the indicator sound? I'd like to muffle - or better still, change using a Raspberry Pi hack - the shrill tinny beep my Seven 485 makes. It has push button turn signals which I guess it shares with earlier R500 models and maybe the 620 series.

I assume it's in the Instrumentation Circuit Board behind the scuttle but my electrical knowledge is limited. Any guidance?

Thanks
