High frequency beep after installing original nav back after testing Android system.

Hello Friends,

I wasn't happy with my Android radio so I decided to install it all back to original.
Everything is connected very carefully and there is not much to screw up with the 2004 facelift model. Its just 4 plugs. 2 from the radio, hazard and one from the fans.

I only just turned on the ignition for the first time in 8 months to make a test. (Try to find a fuse).
The car was standing still for 8 months outside without a battery. Can this be something temporarily because the car was without electricity for so long?

Its not a very hard whining noise but when the car is off and the ignition is on I can definitely hear it and I hate those kind of sounds.

Does the whining noise come from the speakers or from something physical like a fan or other moving parts?

My first guess would be the oscillating vents. Take a look at the link below for some details...

Try turning the oscillation function off to see if the noise stops. See link below for instructions.

There is nothing broken by the way. The oscilating works fine. Only irritating is that I can hear them sometimes and its not a high freq sound but more of a light plastic vibration sound. Thats why I turn them off most of the time.

I was afraid because of the fact that I pulled the plug of the navigation without disconnecting the battery and pulling it back in as well. I did this maybe 15 times for testing (Because of that CRAP android radio). I am really ashamed about this because I thought maybe because of my uncarefulness I blew a few copper spools or condensators inside the radio, making it the high freq noise.

I discovered why It made the beep. I used a fuse splitter and by accident I used the radio fuse to split it up. I didnt use electricity but I only used the pulse of this fuse to turn on a relay. Even that little pulse made the beep quite hard. The beep is gone for I guess 80%. I didnt really had the time to test but It seems lot less then what It was before.

Now I need to find out what fuse isnt so sensitive right there on the passenger side what I can use to get the voltage. A wise lesson for everybody who is using those double fuse splitters.
