Sei que nas Avant´s está na lateral da mala, do lado contrario do amplificador e subwoofer, e nos sedans???

Check the "ZF" connection on the back of the HU, that connection, via a small coaxial cable, and a FAKRA connector, is involved with sending +vdc to power the antenna amplifier, and is also used to send "received signal strength" feedback from the HU back to the Signal Diversity Antenna Switching incorporated within the antenna amplifier.
Aside from that, there is a connection to ground, via the Convienience Control Module, that is functionally associatied with the anti theft security implimented in the SymII. That ground connection must exist or the unit will not boot up. Boot up state is seperate from the ON/OFF state when in normal operation, but must be in normal status before any other response can occur. The security anti theft ground connection is often used to disable the HU when it is not installed in the OE dash mounting bracket.
The Diversity Antenna Issue
Before progressing in the retrofit, the issue of the two different antenna systems used by the B6 and recent B7's must be addressed.
The B6 diversity antenna system brings two leads to the head unit, the main HF antenna (round connector) and the ZF diversity switching lead (FAKRA connector). The HF line carries the main signal (FM/AM) to the radio, while the ZF line acts as a communication bridge between the radio and the antenna module in the rear. The head unit instructs the module via the ZF which of the two antennas to switch to for the best signal.
In newer B7's, the antenna system has changed. Rather than having a ZF and HF connector, two HF connectors (one from each antenna) are brought to the head unit. This I believe allows antenna switching decisions to be made directly at the head unit. As I have not seen the new B7 system in person, I can't elaborate more on the components involved in this layout change.
As the Symphony II+ will only be able to use one antenna in the B6 there will be a slight degradation in FM reception. But if you live in an area with excellent FM propagation, the effects should be minimal for most stations.
The Symphony II+ has a dual FAKRA connector. The left connector (3) is the ANT 1 connection and handles both FM and AM signals. The right connector (2) is the the ANT 2 connection and only handles FM signals. For completeness, point 1 on the diagram is the QuadLock connector.
To attach the existing HF connector to the Sym II+, you will require an antenna adapter similar to the one pictured in the Required Components sub-section. Plug your HF "barrel" connector into it's respective mate on the antenna adapter. Tape-off the ZF connector in the center console as it will no longer be used.
Radio Coding and Fault Codes
As your particular sound system configuration and the one of the vehicle that your radio was previously in may vary, recoding of the radio may be necessary.
Log into VAG-COM, choosing controller 56 - Radio and the coding option. The coding scheme of the Symphony II+ is as follows:
0?x0xxx: Options 3
+1 = Analog Input (AUX)
+2 = Multifunction Steering Wheel
+4 = Telephone
0x?0xxx: Options 2
+1 = Digital Sound System
+2 = CD-Changer
+4 = Satellite Radio
0xx0?xx: Options 1
+1 = Leather Interior
+2 = Diesel Engine
0xx0x?x: Sound System Correction
0 = Sound System (No passive Speakers/No Correction)
1 = Sedan/Coupé with passive Speakers
2 = Wagon/Avant with passive Speakers
3 = Cabriolet/Roadster with passive Speakers
0xx0xx?: Country
1 = Europe
2 = North America
4 = Japan
5 = China

If your Symphony II+ was not outputting any sound, the second-last value (from the right) is the value that affects whether your sound system employs standard amplification or Bose/external amplification.
After successful coding, clear any fault codes that may be present in the radio. Because of the diversity antenna issue mentioned previously, you will encounter the following fault code that will refuse to clear:
00821 - Antenna 2 for Radio (R93)
011 - Open Circuit
Simply the Symphony II+ is telling us that there is no antenna attached to the ANT2 connector. Disregard the fault.
