am I getting paranoid? I mean more than usual?
 

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..

i know it might sound crazy but here it goes.....
Does your car have park assist? When you do or hear this are you on reverse ?

No assist and not in reverse.. Literally few sec after engine start, before I even touch anything else. Usually I wait until rpm drops anyway.

Whatever crazy idea you have.. Put it on.
Experience says its the crazy ideas that bring the answer. Like "microwave doesn't work- did you switch the socket on?"


Seriously, I have no idea what that sound might mean.
Do you know scream of brakes? That high pitched nerve wrecking...
Take that. For 1 second. No fade in no fade out. Car stationary, if someone wonders.
And not too loud either..

What was that?
 

Afternoon Thomas, could your mysterious noise be your Mirror Spiders snooze button? as you have so rudely woken him?


Just a thought, ok,got me coat on.....

Keith.

Have you got a handsfree with Bluetooth fitted. If so, it will be the Bluetooth looking for your phone.

Interesting..
I do have Bluetooth adapter, yes. Fitted it myself- tapped into iPod connector.
But every time it happened, I mean that beep, it was with radio OFF...
So I'm thinking link from iPod adapter would have to be live even with radio off..
Quick test- if it is so, then I should hear something by starting iPod "by hand"..

Unable to test...
With radio off and engine running, I've got Volvo logo on iPods screen and no controls on iPod itself.
But I noticed something else entirely:
I'm sure as hell when I turned radio off few days ago it was set to cd multichanger (iPod adapter)
Right now, after I turned it on it was set to FM.

Is it possible that radio gives beep when its off and receives "traffic info" message over FM?

And I checked wiring for bluetooth- disconnected. Well.. I haven't been using it for over a year now..

Pardon my ignorance but why would you have wiring for Bluetooth.

Well. I'm ignorant in many things. There's no one that knows all..

Phone=>radio link=>Bluetooth receiver=>electrical cables=>radio unit

Therefore by "checked Bluetooth wiring" I was saying: I checked connections between Bluetooth receiver and radio unit.

Beep!

Then also, please pardon my ignorance.

Why not instead:

Phone=>electrical cables=>radio unit
