Hi all. It's been a long time since I posted, but I finally got around to installing my Nokia car kit using the extremely helpful tech notes available at Audiworld.

Everything works perfectly with one exception - when I attempt to use the TT's internal microphone, I get some serious feedback that manifests itself in the form of a long beep. I've doublechecked all connections, but still get the problem. For now, I'm using the external microphone that comes with the Nokia kit, and everything works fine. Still, I'd like to get the Audi microphone working if possible. I've read that Audi's microphone has a preamp that overdrives kits, but I haven't read that anyone's experienced feedback.

Any thoughts are appreciated. If worse comes to worse, I'll stick with the Nokia external microphone since the speaker system and radio mute were the features I wanted the most.

compatible with other circuitry.
your statement that you didn't use the mike compensation circutry is a key.
try this, it helped.

Also, are you getting any input at all thru the internal mike?
That is, can you caller hear you thru this mike?

I will try the compensation circuitry this weekend. I'm not getting any input at all through the internal mic. This is because I'm actually unplugging the control box/RJ-45 mic connection and replacing it with an intact Nokia mic from an old car kit.

When the internal mic is connected, the caller on the other end can hear me, but barely since the beeping/feedback sound drowns me out.

Hey Jeff,

Here's another question for you as a Roadster owner. Did you integrate your car kit with the internal Audi cellular antenna (mini-UHF connection behind passenger seat in roof well)? And if so, where did you run the cabling? I just looped it up and over the seatback, which is a bit ugly when the top is down. Was hoping for a cleaner way to do it.

JustJeff

in the well where the top is stored.
it's a pain to get at, but you can run a cable from there, into the cabin.

NorTTon

Yes, I found that, my question is whether there is a more direct (e.g. hidden) way to connect an RG-58 cable from the cubby connector to my Nokia kit *without* going up and over the the back of the cabin and down into the cubby. Right now the cable is visible when the top is down, and the cable interferes with the boot cover.

JustJeff

well, no, you hafta route the cable behind the plastic piece behind the seats.
