I understand the 3 & 6 pin CD Changer cables normally reside in the trunk, if they're not being used.
In my particular installation, I also had an OEM iPod Interface installed by BMW at the same time they did my NAV upgrade.
When I took my NAV head unit out to see if I could find the 2 - CD Changer cables for my DICE MediaBridge install, I noticed that
the iPod kit requires the use of 4 wires from the 6 pin CD Changer cable, which need to be extracted from the main radio connector
(see http://www.madrussian.net/m3/diy_ipod.shtml) and installed on the iPod retrofit supplied connector.
I guess I just have to work backwards and try to restore my NAV system back to "stock", and extract the 4 wires and put them back
in their respective pin positions.
If someone has done this already, any help would be appreciated.

Thanks.....

Has anyone ever found a phone kit that makes an active high signal for TEL-ON without any relays or transistors? I think the Audis and the Mercs got the FAKRA 40 way connector with TEL-ON so maybe it's a more common signal than just on BMWs.

For after-market phone kit, just hook it to 12V accessory.

TEL ON does not indicate that a call is in progress. It is almost always 12V.

In a factory BMW phone setup (e.g. a ULF), the following happens:

* TEL ON is always on (+12V) when the key is on accessory or ignition.
* If you turn the key off when no call is in progress, TEL ON returns to low, 0V.
* If you turn the key off when a call is in progress, the BMW phone module remains turned on, and the TEL ON remains high at 12V for the duration of the call. This keeps the radio/amp/ turned on (yes, really, even though key is off/removed) so you can hear the call through the car speakers. Once the call ends, TEL ON returns to low, 0V.

So, unless your Parrot etc is capable of remaining on when the key is off, just hook TEL ON to the accessory 12V (aka Terminal R).

I've checked all this on a E38.

I have been using the Parrot Mki9200 with teh Unika interface for two years now without issue. When In on the phone the factor BMW radio says "Phone" on the interface.

Hope this helps
