The guide is strongly derived from a great job of hsd92 based on AUDI MMI 3G+ from the forum

audipassion.com. Original discussion is at this link:

Touareg RNS 850 personalization has been possible due to its similarity with the MMI 3G+ system and

thanks to the support of the following people:

‐ congo (developed the DataPST.db modification script and debugging)

‐ frankiegom (supported the RNS 850 debugging)

‐ Windstar (supported the RNS 850 debugging)

‐ miazza (supported the RNS 850 debugging)

Disclaim:

Even if this tutorial has been verified on some RNS850, I do not take any responsibility of what you are

doing; everything you will do , it will be at your own risk.

1. Prerequisites

In order to activate the VW CAR‐NET functionalities, the following tutorial has been validated on:

‐ VW Touareg (year 2010) – RNS 850 without SIM – FW version K0821

‐ TP‐Link MR3020 wireless routers

‐ Huawei E156G HSDA USB 3G Stick (E3131 3G, E8278 and E3276 4G should work either)

(If you have in house any USB dongle it is worth to try it before to buy one of the above).

2. Script installation via SD cad In order to install the CAR‐NET services, some modification shall be performed in the RNS‐850 Firmware.

These modification have been all collected in the below reported installation scripts included in this zip:

a) WiFi Install MMI‐3GP‐GE‐WIFI or RNS850‐GE‐WIFI (they are identical script with different name)

b) GE and Online POI Activation GE_ENABLE (RNS850 specific)

c) Diagnostic MMI‐3GP‐Diag‐v2.01 or RNS850‐Diag‐v2.01 with modified IP ping address

d) Uninstall MMI‐3GP‐GE‐WIFI‐uninstall or RNS850‐GE‐WIFI‐uninstall ?

Notes:

Scripts a) and b) are mandatory to be installed and are better to be installed in the order as they are

listed.

The Install script a) shall be run only once. In case of need for a new fresh install, the uninstall script

shall be run first; in this case look at the below warning.

The Diagnostic script is not mandatory but it is very useful in order to verify correct connection of

the RNS 850 system to internet.

GE and Online POI activation script modify the DataPSt.db by adding the necessary records; it also

saves a back‐up of your original DataPST.db in the SD card. I suggest to copy it in a safe place on

your PC for any possible future need. The modified DataPST.db is also saved in the SD as installed in

the RNS850.

WARNING: The install and uninstall script are interacting with the KELDO map activation. So after script

install, it might be necessary to reactivate the MAP with KELDO script.


In order to install the scripts, the relevant archive content (one archive at the time) shall be copied on the

root of the SD (run.sh shall be on the root) and the install process is the same for all of them:

Turn on the engine and wait two minutes to allow RNS850 to start‐up; verify that system is fully

booted by pressing all the buttons and verify nominal behaviour of all functions. After this, wait

another 30 seconds.

Insert SD card in the left card slot (SD 1) of the RNS850 Multimedia BOX and wait for the following

screen:

Tap on screen or press any key or turn the rotary knob one notch to start the script

Wait and do not touch anything until the following screen is displayed:

Again, tap on screen or press any key or turn the rotary knob to complete the script installation.

Remove the SD card and reboot the RNS 850 by pressing [NAV] + [PHONE] + [Central Knob] at the

same time.


3. RNS 850 Configuration with Green Menu

Among the others, the installation script

activates the Green Menu that can be

invoked by pressing simultaneously [SETUP] +

[NAV] buttons for about 5 seconds.

Using the rotary knob, scroll down to

“Diagnose” and press on the rotary knob to

select the submenu (from now on we’ll refer

to this process as “selecting” an “option”)

Select “Coding”

Select “internal_modules_1+2”


Uncheck all boxes (same as screenshot)

Using the central knob, go up to “…” and go

back twice to “Diagnose”.

Select “Settings”

Select “wlan_settings”

Check WLAN activation box.


go up to “…” and go back to Select

“tel_settings”

Check NAD activation box and Exit Green

Menu by pressing the TEL button.


4. Configuring the RNS 850 Wi‐Fi Hotpot

Images are in Italian … sorry…

Press on SETUP button and select Connections

Scroll down to WLAN/internet and select it

‐ Check WLAN box

‐ Enter the Access Point Name you want ‐ Enter the password you want ‐ Make sure WLAN active is set to “visible” ‐ Your WiFi hotspot is now active


5. Router Upgrade

Download the latest firmware from the ofmodemsandmen website: http://www.ofmodemsandmen.com/download/MultiWeb310/mr3020‐v1‐lite‐310‐MW2015‐03‐14.zip

Verify the latest version on the site despite the below link:

http://www.ofmodemsandmen.com/downloadsh.html

Unzip the file, power on the Router and plug your laptop into the router LAN port.

Start up your browser and go to http://192.168.0.254 :

- Go to System Tools, then Firmware

Upgrade

- Click on Upgrade

- Browse to the downloaded unzipped

.bin firmware file

- Click on Open


When asked:

“Are you sure to upgrade the firmware ?”

Click on OK

Wait while router reboots…

Note:

If you are using a router different from the TP‐Link MR3020, please make sure it is a model supported on the

OfModemsAndMen.com website; download the corresponding firmware and follow the website’s

instructions for upgrade.


6. Router Configuration Depending from the FW release that you will install, the router web interface might be slightly different from

the images reported in this tutorial. Anyhow the web‐if is quite user friendly and all settings can be easily

found also in latest FW release.

Connect to http://192.168.1.1:

Click on : Login

Click on Go to password configuration

(in the yellow box)


Enter the new password (twice)

then click on : Save & Apply

Go to Network then Wi‐Fi ‐ Click on Scan

Select your RNS850 SSID (Wi‐Fi network)

then click on Join Network

- Enter your WPA key in the WPA

passphrase field

- Enter « wifi » in the “Name of the new

network” field

- Select lan in firewall rule ‐ Click on submit


Enter :

- auto for “Channel”

- 15dBm for “Transmit Power”

Click on “Advanced Settings” tab

- Choose your country for “Country

Code“

- Enter 1 for “Distance Optimization“

field

- Click on “Save & Apply“

- Go to the Network menu and click

on “Edit” on the LAN line

- Change IPv4 address: 172.16.1.254

- Pick 255.255.255.0 for Netmask

- Enter IPv4 broadcast : 172.16.1.255

- Click on “Save & Apply”

- Reboot router


Reconnect to router to http://172.16.1.254:

Go to the Network menu and click on Edit in line WIFI

Change the Protocol field to “Static Address” ‐ Click on “Switch protocol” Note: In the latest router FW release the switch protocol button is not present and is not necessary.

- Click on “Setup DHCP Server”

(at bottom of page)

- Enter IPv4 address : 192.168.2.1 - Enter IPv4 netmask : 255.255.255.0

- Enter IPv4 broadcast : 192.168.2.255 Go to “Advanced Settings” tab (under Common Configuration) Note: This setting is specific for RNS850 and is different from the Audi MMI 3G+.


- In “DHCP Server” (bottom of page)

- Enter 20 in “start” field - Enter 30 in “Limit” field

- Click on “Advanced Settings” tab

- Click on Force flag: “Force DHCP on this network even if

another server is detected”

- Add two DHCP options (click on + to add a line):

- 6,8.8.8.8,8.8.4.4 - 3,192.168.2.1 - 15, ‘’yournetwork.local‘’ *optional

(I have not done it)

- Click on “Save & Apply”

- Input your cellular operator data in the “Modem / Connection” page

Example :

- APN : orange - Username : orange

- Password : orange - Click on “Save & Apply”


7. Diagnostic and Trouble shooting In case the internet connection is not established, the Diagnostic script is quite useful in order to

understand the situation. Once installed, the Diagnostic script shall be executed from the Green Menu:

Green Menu Config Show IP Config

If installation is correct, the following should be your situation:

MMI IP: 192.168.1.1

Gatway: 192.168.2.1

All PING: OK

The first PING is configured to RNS850 Gatway 192.168.2.1; if this is OK and the other are KO, this

means that most likely your config is correct but no data is available from your SIM.

Check if you can access internet from a laptop when connected to the Ethernet cable of the router.

PING sites can be edited in the Diagnostic script by editing the getStatus.sh file (this of course requires a

reinstall of the diagnostic script).

8. Points to be further elaborated For systems that have built‐in SIM, the procedure should be almost the same (at least this has been

tested by Windstar). Of course the part related to router configuration is not applicable.

The only difference is that from Green Menu it is necessary to uninstall the Fairmode or, if preferred,

disable the Install Fairmode inside the install script.

Street View is not working on all systems. Especially for those car older than 2011 this feature is not

available.

In order to support the reverse engineering on this subject, it would be useful to share DataDSP.db for

systems that have a working Street View. DataDSP.db is saved on the root of the SD after the

execution of the GE and Online POI Activation script.

Traffic Online is not working. It seems that the license activation is an issue to be further elaborated.
