Octavia stream mp3

Hi everybody,

I know lot of post released alredy in the past,

But I just have got my octavia 2 2005 yesterday.

I wish to get help with the stream mp3 security code.

One label on the radio body with lot of different things:

Radio Stream

PD: 3507

HW: 0019

SW: 0040

1Z0035161C

Visteon

VP68BF-18C815-BA

10R-022432

SKZ7Z3G0041205

If anyone can help me with the security code, please do.

Also I ask everybody, if you can write me what things can be connected to the head unit?

I mean for, 6 disk cd charger is already factory connected.

Anything else can be connect through that ISO cable?

Like amplifier, subwoofer box ect...

Please help me.

Thank You.
