    B6 A4 after market Head unit install?

    right lads.. I have a single DIN Chorus cassette head unit in my a4. I took it out and was going to pop in a cheap Nikai (maplins special) head unit just cos it has CD, Line In and SD card. It's odd though cos I can't find a switched live on the power block. I've been in there with a multimeter and there's a permanent live but no switch. So how the hell does the existing head unit have a switch? To be fair it doesn't turn off when the ignition's off. You need to turn off the ignition and remove the key. hmmmm. Is there an autoleads ISO adapter I should be using? I don't want to keep the power permanently connected. I spliced the live and switched live together to give permanent 12v but even with the facia off I could hear an intermittent popping through the speakers, suggesting there's too much going on there and I'd be seeing a flat battery quickly.

    And Do I need to think about a PC5-52 amplified aerial?
    The Autoleads website seems to suggest a PC9-401 although the chorus unit isn't really listed anywhere for my year of car. Aww man this is confusing.



    Oh yeah... what the hell's this? Is it some kind of mobile aerial? It's hanging down at the passenger side of the dash. Looks like it used to stick somewhere.




    cheers

      cheers Steve. I had a wee look again after posting that and i should have looked closer to start with. it's an aerial and tax disc holder in one. or used to be anyway. I need to find the actual car kit and see if it's of an use and probably get rid of it.

      damn the weird wiring though.....

        B6 A4 you say? My speciality

        You won't find a switched live because there isn't one. The radio is controlled by signalling on the CAN-BUS. If you want a switched live then you will find one on fuse 5.

            Because I have a cassette head unit there and haven't owned a cassette for many years now. The head unit I have sitting there has CD player, line in and SD card reader so It will be a bit handier. I'll probably pick up an OEM audi CD player soon but I do like to pull the micro SD card out of my phone and bung it in the SD adapter so I can play my tunes in the car too.

                I wouldn't mind so much with the CD changer but i'm just using radio only now, which is pretty useless.

                      Guys, I have just bought an 2001 Y plate Audi A4 B6, and want to change my headunit. I have bought the extra ISO adaptor but cant get my Ripspeed DV701 to power up. I have switched the two power leads, and the stereo beeps but does not turn on. Any ideas, before I end up taking it to someone to install for me and cost me even more?

                      Cheers

                      Dan

                        Same problem, you need a switched live. Also check the wiring in the harness as you can send +12v to the K-Line which will make diagnostics interesting.

                        I'm an hour away but bring it up to me if you like.

                            You don't want much do you?

                            Take a wire from fuse 5 as said above. Done.

                              Can I not join the two wires together to make it work?
