I plugged the CK3000 in and ran a quick test last night and a few issues need to be resolved before I can complete the install.
1) No power to orange wire when ignition on - I'm planning to tap the windshield washer circuit since it's switched by ignition and seldom used. Any thoughts on this plan or a better alternative?
2) I plugged the yellow mute wire into the Mute #3(blue). The stereo mutted and phone set up was audible, but stereo did not say "phone" as I was led to believe it would. Is this as good as it gets with this stereo?
3) Lastly, phone audio was very loud and distorted. I understant a 5k resistor will tone things down a bit. Which wire do I splice the resistor into (also I could only find a 4.7k resitor, close enough?)?
Thanks in advance for your input!
Try this website, they have adapters to plug it in the back of the radio.<ul><li><a href="http://www.nexxia.co.uk/Car_kit_installation_leads/audi.htm">http://www.nexxia.co.uk/Car_kit_installation_leads/audi.htm</a</li></ul>
It isn't that hard, but you do have to do a bit of custom wiring for the symphony 2 radio. There's a great writeup of exactly what you want to do in the tech article section. I've described replacing the DIN speaker connectors with the phone+/phone- line in pins on the radio.
The things I did:
1. Per the tech article, the mute wire plugs into the back of the radio near the phone +-. Connect the yellow mute wire from the relay pack directly to the mute circuit on the radio (buy a couple of 000 979 133 leads, remove the yellow tab in the wiring plug to connect). If you don't have the plug (if you don't have NAV, you probably don't have the connector), search audiworld for CK3000 and the part number and you'll find the part number for the wiring plug. Others have just used a slide on spade to connect the wiring.
2. You're non-bose from the description. The speaker relay pack is what is doing the audio for you -- that's why it doesn't matter if it says phone or not. The CK3000 manages where the sound comes from by switching to it's amplifier when the phone is active. You can ditch the speaker relay setup. I bought a speaker-level to line-level converter for $15 (probably paid too much) at the local car stereo shop. I picked one pair of the speaker outs from the CK3000 and connected them to the input of the converter. I plugged the output of that directly into phone+ and phone- on my symphony 2 radio. The pinouts are on the sticker on the radio. Leave your old speaker plug in the stock position. Some people have complained that the CK3000 speaker wiring is too small. If you're concerned about sound quality, this is how you avoid sticking the CK3000 into the middle of your speaker wiring.
3. Tap the 74X contact (presuming it exists on your '06) under the knee bolster. Find a chassis ground for the ground piece of the circuit. You then have switched power. I use the same circuit to power a 'fake' cigarette lighter plug under the knee bolster for my XM tuner. This is a bit easier than going all the way to the fusebox for the power.
I hope this helps. Let me know if you have more speicifc questions.
