Audi B6 S4 install

Written By pipe swinger, Colorado on Friday, August 21, 2015

Crutchfield Customer Review (What's this?)

I bought and installed this iPod adapter for my 2005 Audi S4. i wired it in to the glove box and stashed all the wires and the converter brick deep inside the dash. make sure you get the adapter cord they recommend.

Pros: Easy quick clean install, only tool needed was a Phillips head driver for the ground wire.

Cons: Not allot of power. i crank it and can barely hear it with the windows open. Also for $100+ the entire kit should come all in one. the fact you have to shell out an extra $36 for the adapter cable for a iPod adapter kit is illogical to me. why cant the kit just come with everything you need? hence the All-in-one kit!!

Easy as pie!

Crutchfield Customer Review (What's this?)

So, I ordered the USA Spec CAS-AD3 Adapter Cable (I already had the other piece) carefully pulled the factory head unit out, disconnected the existing plugs from the head unit, plugged the new adapter in and 15 mins later, I was done! Seriously, this is so straight forward even if you've never done this before you'll do fine!

Pros: Easy to install

Cons: Should be a bit cheaper!

Bent pins, but plug and play after straightening.

Crutchfield Customer Review (What's this?)

Installed in a 2000 Audi A6 Quattro with a Symphony stereo.

Pros: Necessary for connection. Plug and Play

Cons: A row of pins were angled slightly wich inhibited the plug to slide in immediately. Had to correct their position and it slid right in.

Crutchfield Customer Review (What's this?)

This piece is neccesary if installing in an Audi TT. It simply replaces the standard plug that
comes with the IPod interface unit.
