- I have yet to vag the unit (coming tomorrow afternoon)
- Unit is installed in dash and all plug and play installation is completed.

Now a couple of questions ...

1. The Nav doesn’t see my Phatbox which was running flawlessly with my regular radio ???

2. Is there any other installation that I need to do in my 2004 A4 ? Something about a speed wire ?

I am trying to find more in the FAQ's but there are a lot of em :D

Speed wire isn't required if the unit is coded for an A4 (which should be the case if it's an A4 unit). But the CDC ground wire may be missing (pin 10 in the 20 pin connector, next to the CAN high/low wires). Did you check if that pin is present? If not you have to connect the phatbox to ground or ground the wire in that position coming from the car. In addition to the CDC ground, the RNS-E needs to be told that a CD changer is connected. In most cases it shoudl work without adidtional coding but if you are checking the coding tomorrow anyway, make sure that you code the RNS-E to support a CD changer.
