Hi,
I just started doing some audio work on my 2001 A6 4.2, I found a few disconnected wires and was wondering what they were for. My guess was NAV antenna, reverse switch sensor power and maybe satellite radio?




These are the wires in question...<br/>

Any help would be appreciated....

Thanks ,

Cut the blue wire!!! Don't cut the Red Wire!!! Or was it the other way around???

Thanks so much, but that was my other car.
Just looking for a little help, I have searched the forums, and consulted google to no luck thought I might do better here.

Simple answer: I don;t know. The DB-style connector could be nav or CD changer. The coax almost has to be to an antenna.

I think the DB25 connector is for the OEM phone (analog). Is there a jack in the armrest? Not sure what the other one is...does not look OEM.

Yes the car was originally equipped with a cell phone, has MFSW. What would be in the trunk for the phone?

It has a sym II stereo, the CD changer is in and functioning! I'm thinking the coax may have been for navigation?

I was hoping the white pigtail off the plug to the tail light was to tap the reverse lite power, I'm installing a new stereo with backup cam, gps and Bluetooth. Just trying to get a handle on the routing of wires to the trunk so I don't have to pull apart too much trim.

Thanks

Betting the DB25 and coax are both for the Phone.

It would have been a Motorola phone module.

There were basically software modified versions of the standard Motorola analog mobile cell phone, with a OEM labeled handset in the center armrest.

Usually there was also an interface box that allowed the phone to be controlled and display information on the instrument panel.

Yes, that looks like it. Even has an input for the coax. The two were tie- wrapped together so that is that question solved. I can use the coax to run my reversing cam signal to the head unit maybe, if it terminates there.

I think I can tap off the shifter for the reverse signal, any ideas on the color of that wire or where a diagram can be found for it?

Thanks for the help, it's much appreciated.

It probably terminates wherever Audi put the cell antenna.
