Beep when I turn in my car

[Tyson.burke]

Hey I have a 2004 Subaru Liberty GT and when I turn on the car after about 30 second a beep happens.
I have read the manual and searched for an answer but can't find anything about it. Does anyone know what it means
PS sometimes it's a different tone

I have an aftermarket Sony Erricson bluetooth module in mine, the speaker is somewhere in the drivers side air vent closest to the door. It beeps too. Just once.

Yeah, definitely sounds like a non factory feature. Look for Bluetooth unit like arrow224 mentioned. Or maybe an alarm (less likely but possible). My dashcam beeps when the power is turned off, but I guess you'd notice a dashcam and your beep is not when turning off.
