Yes, s'me again.
To the point:
Happened few times by now, last time quite few days ago..

When I start the engine, radio off, I'm getting a single, quite loud, about 1 second long "beep" on me speakers. Kinda... 2-3 seconds after motor starts.

First time I thought its my imagination, but it comes back..

Second time I thought my phone- cradle being on the vent by drivers side mirror.

Today I had my phone in me pocket, and sound definitely came from front of me.

Any if you encountered something like that?

For reference:

OU52 (MY03) V70 petrol 170hp, HU803 with Dolby (premium?)

No warnings on displays, nothing..
