I've got a Samsung SCH-3500 call phone. Has anyone integrated this (or any other non-Nokia) phone into the A4? I'm looking to take advantage of the special features like muting the radio on incoming calls, using the built-in microphone, etc. Thanks!

WHile I am updating my FAQ (look for it within the week), the approach is identical to the nokia.

All true handsfree kits (those say that they require "professional" installation) use the same wiring scheme:

An unswitched 12v supply for charging

A SWITCHED 12v supply for signaling when the car is turned off.

A ground

Speaker output (2 wires)
Mic input (2wires)

You want a kit that supports radio muting, otherwise the Audi radio will not mute, and the speaker output will not get directed to the built-in speakers. In teh case of Bose, its a dedicated speaker, but controlled my the head units, in the case of NON-BOSE, the speaker output from the handsfree is routed through the headunit and user selected to go to the right or left front speaker.

Some kits may have other "features", but those are the basic ones you need.

To interpet the nokia FAQ for another brand, just substitute the correct wire from your non nokia kit.

In the case of the new FAQ, it will eliminate the RJ45 box in the older FAQ, and places the handfree controls under the rear seat, a far more accessable place from the trunk (DB25 connector and antenna), and the console (the cradle).<p>

First of all, Thank you for an amazing FAQ! Seeng how professional this DIY Mod can look has convinced me to buy the Nokia hands-free module.

I have a question. I have a 00' Avant 1.8T with Symphony head unit (no Bose) If I replace the factory front door speakers can I still use the hands-free phone? I heard that Bose setup used a two coil speaker removing which will eliminate the phone speaker. Is that true? Is that also the case with non-bose systems?

Changing door speakers won't affect a non-bose system, since the output is run through the head-unit. Output is selectable between right and left front speakers via the radio (look in the users manual for the radio. It explains it pretty thoroughly.)

The Bose system, has a separate speaker (and grill) for the handsfree speaker, that's integrated into the car. Separate from the radio in the regard that the handsfree output is separate from the radio, but the speaker doesn't activate unless the radio is muted via the ground wire (stereo muting).<p>
