What are these connectors for?
 

I have a Dynavin N6 on the way and was poking around in the back today and came across these next to the bluetooth module. Does anyone know what they are for and what they connect to? I have NAV and DSP and everything is connected and working. I'm especially curious about the coax cable as one of the things I want to do is use the factory GPS antenna for the Dynavin, and I'll need a 50 ohm coax from the head unit to the back anyway.

wiring for an optional 6-CD changer

I already have the 6 disc cd changer, so that's not it.

TV/video input (analog) on Navigation screen. Quite the rage before everything went digital.

U do not need those connectors any more

Cool. Does the coax cable run up to the head unit?

I think....

Purple goes to bluetooth module....

3-pin connector is DEFINITELY a cd connector.....power-ground-Ibus.

Maybe PO had DICE/Grom module?

Well, my bluetooth module has at least two connectors plugged into it that I can see (on the top. There may be others on the bottom), and one of them is a coax. The bluetooth also works, so I'm inclined to think everything is connected properly.

Nice to know that I have an Ibus connection if I need it. I do have the Ibus USB adapter that I bought to code the NAV screen, but I never did anything with it.

As mentioned previously, I have the 6 disc CD changer in the back, so I'm inclined to think PropellerHead is correct, although I thought the TV module went next to the radio module next to the battery?

In my E39, I installed the TV module next to the 6 CD changer. But I don't really remember what connections I used. The coax connection there looks like the antennae for the analog TV which where separate from the radio and included boosters on each side.

I did this about 15 years ago so I don't remember the details well.

But this could also be the satellite radio connections. They include a coax antenna connection as well. I did that in the E53, but it's a memory that's faded in 5 years as well.

I thought sirius module as well... there are so many of those connectors back there...
