Navi950 retrofit in Zafira C - Happy25 - 15:th-Jun-2025
Hello everyone,
I’m new to the forum and I’m from the Czech Republic. I drive a 2012 Opel Zafira C and I really like this car.
My original Navi 900 stopped working, so I decided to replace it with the Navi 950. I already have the Navi 950 unit, but I read that it needs different microphone wiring. Is that true? What exactly needs to be changed?
I’m not very experienced with retrofits, so I would really appreciate any help or advice. Has anyone here done this upgrade in a Zafira C? Was it difficult? Any problems with wiring, compatibility, or coding?
Thank you very much in advance!

The microphone is wired into the x4 plug.
You can buy a connector off AliExpress and pin a new cable into that and then into the BT module plug saves running a whole new cable.
In terms of programming for unlocking you need someone that has MDI, MDI2 or VCI and knows how to program them, if you have these I can help remotely.

Thanks for the info.
Do you know which pins on the X4 connector are used for the microphone? I found a wiring diagram here on the forum, but on my X4 plug pin 6 is already occupied. Do you know what might be connected there?
Also, could you tell me exactly what type of connector I need to connect to the existing BT module cable?
I have already found someone who can handle the remote programming.
One final (and probably stupid) question: has anyone found a way to install custom apps (Spotify, Sygic, etc.) on the Navi 950?

18pin male one.
A111x4 pin 6 & 16 for mic
5 & 15 is rear camera.
Only way to add things like that is by adding touch screen and the wiring again needs custom programming to enable touch. Then a GROM Vline unit very expensive.
There is another unit being used which doesn't need a touch screen and is cheaper than the Grom but I don't know what the unit is called.

Thanks for the link — this will make my work a lot less messy
.Do you know what might be connected to pin 6 on the original Navi 900 wiring? I attached a picture to my last post, but it seems it didn’t upload, so I’ll try again. Anyway, there is a yellow/brown wire connected to pin 6.
Regarding apps on the Navi 950 — I meant installed directly on the unit, because I’ve seen pictures of some preloaded apps (can’t remember exactly which ones), so I was wondering if anyone has ever successfully installed a custom app on it. Probably not, though.
I know about those units that connect between the Navi and the display, but the Grom is really expensive and my budget is quite tight :/ I found another unit that is much cheaper and looks promising — the Andream Wireless CarPlay / Android Auto. Is this the cheaper unit you were referring to, or has anyone here had experience with it? From the picture, the module has a different LVDS connector, but Navi 950 is listed as compatible. I’ll probably give it a try, since the latest map for the Navi 950 seems to be from around 2018 (correct me if I’m wrong), and I’ll be travelling more often now.
But first I need to get the Navi 950 itself working. Even though the unit is locked, at least I can now hear the turn signal chime.
Thanks again, and I’ll probably be posting here again soon.
