Converting Symphony II+ antenna system for use with RNS-E

Discussion in 'Cables / Adapters / Antennas' started by AudiA4B6US, Sep 28, 2007.

  1. On Saturday (12/31) I drove the Audi since my car was in the shop.
    It was my first chance I had to drive the car since I had done the changeover. I can tell everybody now that the reception on both AM and FM is at least as good as on my Phaeton. I do actually feel, that the AM reception is actually better.
    I tried several AM and FM stations and had the same result.
    Here again I had not made any changes or modifications on the standard TT antenna system.

    Hi John,

    Would you say that FM reception is better if changing the amp than when adding the Golf diversity box? Indeed I need to to something to fix my problem, and having a few vag-com errors is not a big deal to me, so I'm wondering if the diversity box would be sufficent for me?

    Pretty sure it was said in previous posts, but I have confirmed of B7 Saloon (Sedan) non factory RNS-E cars, the only real 100% fix for the ZF fault is a new rear glass and antenna amp.

    The factory installed RNS-E rear glass has an extra trace for the ZF antenna.

    You can see the additional trace in the center of the glass in this B7 RS4 with factory installed RNS-E (no ZF fault)

    And a B7 S4 with factory Sym II+ converted to RNS-E (confirmed ZF fault)

    Hello guys,

    Sorry to dig up this lead thread, but i've just retrofited to my Audi A3 2005 a 2012 RNS-E, now i also want to retrofit the diversity antenna and i found for a reasonable price these two components:
    -
    8P4035225D

    -
    8P4035225C


    I must mention that my car came with a concert single din unit that didn't support MP3.
    will these fit to my car?

    Hi

    Yes I think that would work. Only thing is that I think you'll find only one module i/o two because your car was fitted with a single din one.
    Therefore you'll have to bring an additional cable from the back to your rns-e unit.
    The specialists will confirm!

    Hope it helps

    The retrofit was only required on 2007 and later cars. You have a 2005 model, can you please confirm how many antenna connections are on the back of your current single din unit? A picture would be ideal.

    A 2005 car would not have had a Series II+ radio (they were only introduced with 2007 MY cars) .

    Single DIN chorus - HF antenna only
    Single DIN concert - HF and Diversity

    Guys my concert came with only ONE antenna.
    By the way i have a bad reception on the RNS-E and the antenna related errors on vcds.

    Okay guys I need some help. I have read through this entire thread an am still confused as to what exactly I need.

    My car is a 2007 S4 Avant. The car did not come with RNS-E but I installed it a couple months back and removed the Symphony 2+.
    Since then my radio reception has been horrible.

    I read about the original fix with the Golf antenna module but then people stated that it didn't really help in the end.

    What exactly do I need to replace to get my reception back? Antenna module? Glass? ???

    FYI In the next 2 weeks Audi is replacing my rear hatch (tiny bit of rust near tail light) so I have an opportunity to swap out the glass if needed.

    Thanks very much to anyone that can help me with this....

    Okay so I found and ordered an 8E9035225P antenna booster to replace the 8E9035225AG that is in my B7 S4 Avant right now.
    My dealer ran my VIN against the same car that came with OEM Nav and we have the same rear glass so I don't think I need to change that.
    Just wondering if I need to change the cables? Would like to get everything organized so I don't have to tear apart the car twice.

    Has anyone done this on the B7 A4 or S4?????

    Hi guys, long time since I've been here.
    OK, I know - super old thread but I still have a similar challenge :)

    I've helped to retrofit an RNS-E to a 2004 Audi A6 4B (C6). The car had a single DIN Concert II player. So I suppose it then have HF and Diversity, according to craigyb. It also did have the old BNS navigation system in the FIS. (I've disconnected this - AFAIK it is only a GPS antenna going into this unit, antennawise)

    The issue: The radio barely works at all. We tried connecting a external antenna - to rule out the obvious (RNS-E fault). Works perfectly.
    We have the antenna adapters from Kufatec, but I suppose these do not utilize the diversity system?

    As I understand it:
    Option 1 - install VW antenna unit - cheapest and less hassle. Will still have VCDS fault for the diversity
    Option 2 - exchange A6's antenna booster, this means: find out where it is, revision and which revision to exchange it to. Then source it and I also have to make the cables that JohnS3 did. Correct?

    Option 3 is to install a non-OEM glass antenna of some kind, but that seems quite idiotic when you have a great antenna system in the first place.
