NavPro connectors - possible hack to enable carnet on MIB1

[fredgroves]

Ok, I think I am starting to understand this stuff. Thanks Kevin!

Hi guys,

Sorry for digging up such an old topic.
Just here to inform you... I enabled WLAN Hotspot functionality on the Discover Pro MIB1 (without Premium Phone stuff).
Also, I took the glove box device out... opened it up. After googling a bit, I found that the Premium Phone module is indeed inside this device, when you've ordered it. It seems hard to retrofit.

Wlan is functioning perfectly, the only problem is: it doesn't have any internet access due to the absence of a SIM-card. Neither can it use my Phone's internet over Bluetooth. RSap isn't possible.
My final hopes are set on turning the Discover Pro into a Wlan Client, instead of a hotspot. This should be possible, I've seen several posts on German boards regarding Passats with a Wifi router in the trunk to enable internet connectivity on the DPMIB1. All we need is... the right setting.

Anyways, for those with VCDS, here's how to unlock WLAN Hotspot mode:

Module 5F
 Login 20103
 Long Coding:
 Byte 15, bit 4 = 1 (Phone NAD)
 Byte 24 bit 3 = 1 (WLAN module)
 Adaptation:
 WLAN: On
 (7) -Vehicle WIFI_Hotspot configuration: On
 (17) -Vehicle UPnP configuration: On (will enable DLNA)

 After setting this, reset the machine by holding power for ~ 15 seconds.
 You can now find the WLAN settings in the menu.

Thanks for that. Sootchucker on here has done it but I wasn't sure what settings he'd used. I'll give that a go tomorrow.

Cool to read that

Still strange that VW is saying in all documentation: WLAN is inside the additional Phone module, while it actually in the same chip as the default bluetooth chip on board of every Discover Pro. Let's hope I'll be able to enable WLAN Client soon.

Wow I tried the hotspot one on its own before, will be turning this on, have plans to turn a rasp pi zero into a wireless music player from a usb hard drive as I am fed up with the normal system loosing connection to the hard disk and its inability to show the full collection of music on the hard disk. Bluetooth and the pi seems to be a little badly set up at the moment.

Yeah, now you can use DLNA over WLAN



So far, here are my findings (to get back on topic) so far:
 - WLAN is on same chip as bluetooth and is available in all Discover Pro devices. (the exact opposite of what VW/Audi keeps on telling us!!!)
 - Developer menu can be enabled through Adaptation.
 - Developer menu can be opened by holding MENU for ~20 seconds
 - Screenshots can be made by pushing the right button, once developer-menu is enabled
 - Overlay view of screen elements can be enabled by pushing and holding CAR button, once developer-menu is enabled
 - Overlay view of screen data/names can be enabled by pushing and holding TRAFFIC button, once developer-menu is enabled
 - Skin can be changed through Debug options in Developer menu
 - Loudness can be disabled through the Green menu in the Developer menu
 - Mirrorlink button in main menu can be enabled through Debug options in Developer menu
 - WLAN is available after enabling Phone NAD bit in long coding(which enabled Premium Phone)
 - DLNA is available after enabling WLAN (this is port 49152)
 - Wlan packets can be sniffed and saved to SD through the Green menu in the Developer menu


Some screenshots I took:
The Developer menu:


The "Green" menu:


The Mirror link button in the main menu (non functional):


This is inside the glove-box part of the Discover Pro. The upper right area is reserved for the premium Phone module. Those two connectors at the bottom are named "HDD" and "MMX", but I don't know this industry standard so I wouldn't know how to connect to them. I didn't find the solid state drive... it's probably on that nvidea board


Googling for chip numbers, here's what I found as well:

The little chips with the blue are probably the SSD ram chips.

I tried all of this with a Disco Pro that has no Sim card slot and it didn't work. 

What I found was I had no bit settings in byte 15 and 24 so I tried them anyway. It accepted the changes although when I re-queried the long coding it didn't accept the byte 24 setting. Byte 15 settings was accepted and it gave me a premium phone option in the phone settings menu, although ticking it proved fruitless as it couldn't activate the premium phone (obviously).

I did find further down though there is a wireless client option near the UPnP and WLAN Hotspot settings, so turning that one might turn it into the client mode you want.

I have software version 0376 and part no. 5G0035020D.

thanks for your input.
It seems to me, that some (older revisions?) of the DPMIB1 do not allow people to turn this on.
I know about the WLAN Client bit, but haven't been able to get it working. But... I suspect there is some combination between the bits that I can set:

- WLAN Client
- WLAN Hotspot
- WLAN enabled
- Phone NAD
- UPNP

It's a matter of trying all logical combinations...

[fredgroves]

Of course WLAN client, even if it does enable, will have SSID and password settings... whether those are set in VCDS data or hard coded, I guess we won't know. Although you should be able to see if trying to connect if you sniff the wifi... that will give you an SSID.
