Discover Media retrofit

[aswigon]

Mic in pins on Discover are pins 1 and 7 on the green 12 pin connector block, same as it was with the RNS510.
Check your adapter harness that it has the pins being fed from the car harness to the Discover connector.
There is no coding required.
Make sure your old bluetooth module has been physically disconnected.

Okay I am way confused now. My head unit came with 2 looms,

Carplay which has a green header and then a separate microphone with a blue header.


Here is a shot of the 2 blue headers with the original RNS510 one on the left.

I feel like I am being a total noob with this. Do I not need my factory Bluetooth module any longer? Where does the installed factory microphone currently attach to?

Sorry for all the dumb questions.

Original bluetooth module comes out of the car. Discover has bluetooth module integrated inside the head unit.
If you had voice control with your existing RNS510 then the factory mic would have been wired into pins 1 and 7 on the green 12 pin connector block. Then mic out from pins 4 and 9 go down to the bluetooth module.

If you ONLY had bluetooth mic, no voice control, then the mic pins aren't actually connected to the head unit at all, they only connect to the large 54pin connector.
If that's the case then you need to get those pins up to the back of the head unit. Easiest way to do that would be to just run a pair of wires from the back of the head unit down under the carpet to the bluetooth wiring loom (assuming it's in the factory location) and splice into the mic wires (normally black and transparent wires, next to each other can't remember what pins).

If your bluetooth module is behind the climatronics panel then just pull the mic pins out of the large 54 pin connector and plug them into the green 12 pin connector block on pins 1 and 7.
They are at the opposite end of the RVC pins on the blue connector on the right in your pic above.

Had the full voice control module and bluetooth module is under drivers seat. Will disconnect as suggested.

Appreciate your guidance on this and will take a further look. The green header / loom that came with it has the USB and 3.5mm connector but the 3.5mm wires appear to be using pins 1,2 & 7. The USB obviously goes to the special port on the back of the unit but also to pins 4 & 5.
I found the following pinout diagram and I think this is correct for my unit based on what was supplied and the experiences I am having with configuration.


Is there a recommended way to swap the pins out? I feel like I need to take my existing MIC pins and move them to 1 & 7 on my blue connector because when I use the supplied microphone (blue connector) it works with the head unit. The other option is to install the supplied microphone but that means pulling heaps of stuff apart to run the cable which I would prefer to avoid.

Any ideas are appreciated. I feel like I owe someone a beer or 2 already.

[kamold]

Yes that pinout is correct. Sorry I was being a bit confusing there ignore the colours of the connector blocks as the RNS510 connector at that location was green, its blue for Discover but colour isn't important, just the correct pins in the correct locations.
Mic is on pins 1 and 7, RVC is on pins 6 and 12.
3 and 4 are USB detect pins on the other 12 pin connector block. Aux goes there as well but is pretty much obsolete these days.

To swap pins just use a jeweler flat blade screw driver.
Open up the connector if you can't already see the release pins (there are different manufacturers of these if they are factory then you need to open each side by prying them open, then you'll see the pin locking lugs)
Push down on the triangle shaped locking lug you can see on the long flat part of the pin from the side, while pulling it back out of the connector block.
insert till it clicks into place then push the plastic locking parts back into place (if it has them)

Thank you so much. Will give it a go now. Apologies for confusing you with the colour etc.

Is there a way to get Climatronic output showing on the Discover like the RNS510 had?

Hopefully the RVC install after this will be less painful now that I am starting to understand how it all hangs together.

[kamold]

No there is no climatronics display.
RVC just needs to be coded in the Discover at byte 19 I think (RVC low) and make sure if you have PDC that it's also coded for RVC.
Do you already have PDC display working in the Discover? If not it needs to be enabled in adaptations. It's on infotainment databus.

[aswigon]

Not sure if PDC is working yet as haven't tested but will check adaptation. Thanks for the additional information.

Are there any other wires I should take from the RNS510 connectors and bring across?

[kamold]

If you have a proper harness it should bring all the pins across to the correct location.
However the cheap Chinese ones don't have all the pins just the main power and speaker wires so you might have to end up bypassing the harness and plug the pins directly onto the connector block that plugs directly into the disco.

[aswigon]

So to get PDC working I also had to do the following:

ENG122229-ENG117710-Car_Function_List_BAP_Gen2-parking_assist_0x0A,activated
ENG122229-ENG117711-Car_Function_List_BAP_Gen2-parking_assist_0x0A_msg_bus,Terminal 15

Also had to turn off RVC option in long coding as I don't have it installed yet.

[aswigon]

So this is probably a dumb question but I have now installed my RVC and completed the VCDS coding. Camera works fine but OPS no longer appears.

I have seen screenshots where both appear on the screen at the same time. Is it possible to achieve this? Can the screen function be switched between camera and OPS on the fly?

Have I missed something obvious?

Thanks.

[kamold]

Need a newer PDC module

[aswigon]

Ahh yeh I remember that from your original post now that you mention it again. Will investigate but guess I would need to find someone local with VCP to make the required settings change.

Any suggestions on the best place to buy the PDC module?

Is the PDC module located behind the drivers side rear wheel?

Thanks again.

[kamold]

PDC is in different locations in different vehicles. What is yours?

What's the part number of your current PDC module?
