PC-5200, MI-2200, MM-2100, not working, different questions

[wireless-dj]

Hello from Germany,

I found this Forum, and it seems, that all VDO Dayton Experts are here. In Germany, nobody was able to answer my questions, so now I try here. I don't speak your language, and my english is not the best, but I hope, you understand.

I want to install my "old" PC-5200 in a new car, and expand with Multimedia. My equipment is:

- PC-5200 Navigation System,
- MM-2100 Monitor,
- MM-5300 Monitor,
- MI-2200 Multimedia
- DV-6100 Player.

1. If I connect the MM-2100 to PC-5200, it works. If I connect
the MM-2100 to MI-2200 I get no picture. Why?

2. At the PC-5200 there's an "accessory" Pin (A5). For what it is?

3. At the MM-2200 is a little jack-connector in the cables, that
should be removed for use with DV-6100. The jack seems to
be empty and not wired. For what this is?


Thank you !!!!

Volker
