    Having looked through some threads i think i may have wired my new pioneer up wrong can someone yea or nae it for me please.

    Head unit to audi power loom(had to move a pin on the audi wiring loom to get live feed? that right)
    Audio to pc9-409 then amp power to remote live from hu.
    Having problems finding the right adaptor for the aerial(tried pc5-52 cant seem to get a reception, where should i take a live feed from?)

    My stereo switch's on and off with the ignition and holds it mem with no problems for the last couple of weeks. (no electrical or vagcom errors)

    Thanks in advance

    You should be using pc9-410 which connects to the RCA output from the Pioneer. The 409 seems to be for the A4 cabrio only and uses the speaker output which is not a good idea.
    The live feed for the antenna amp adapter should either connect to the remote live or the power antenna feed on the Pioneer.
    That adapter is correct but it won't do anything without power.
