Hello everyone.
four months ago I retrofitted a discover pro in my golf 1.4 tsi. From stock it had a composition media and a version of the virtual cockpit that no have device maps. It is the clúster 5G1 920 790A.
when I disassemble the pieces of the dashboard I see a most fiber cable that connect the dashboard with the radio. But why a most fiber if vw put a radio without navigation?
finally I can not work the maps in the AID 😕😕
any suggestions or ideas for this?

It’s not just maps that go from infotainment to dash dude, so presume they use the fibre optic for other stuff too
Also if you haven’t nav you won’t have maps on the AID

Hi vwjap.
the last paragraph I don’t understand. Please can you explain more?
it is very interesting.... Now with the discover pro I have maps but only in the discover screen....
All the rest of the features works fine.... including the navigations to a destination in the dashboard..... but the maps nothing..... catastrophe

Ahh so you changed to nav Maybe have a look in the 5f for this little lot
Dashboard_Display_Configuration: navigation_map_transmission_mode: MOST_streaming navigation_map_compression_mode: H264 navigation_map_resolution: resolution_1 crossroad_detail_map_transmission_mode: off crossroad_detail_map_compression_mode: RLE coverart: On stationart: On call_picture: On crossroad_detail_map_resolution: resolution_1 fastlist_most: Off ability_switch_nav_maps: Off dynamic_icon: 0
maybe this too?
Installation list, specified installations:
Instrument cluster control module:
Yes

Yes I think it is not a codification problem. Maybe it not have any hardware specific and another software specific.
I try all the combinations of the codification posible. And I changed the most fiber cable between the dashboard and the discover pro too ..... but nothing....

My understanding is that the 2 x glass-fibre MOST bus lines is used for flashing the control unit in the dash panel insert J285 (i.e. J285 is flashed via an SD card in the card slot of the information electronics control unit 1 - J794). The schematic for the AID cluster looks a little like this:
As for your maps problem - how did you deal with Component Protection errors in the hex5F and hex19 modules after installing the new MIB?

Hi Don Thanks for answer me. The unit 19 Gateway without errors. the unit 5F with 3 errors, but all works fine. Maps in vC no.
Are you sure that your J285 (5G1 920 790A) has the required display resolution capability of 1440 x 540 pixels?
My further understanding is that the two LVDS lines in my diagram above are used for receiving image data from the information electronics control unit 1 - J794. Check these connections (including the shield).
Component Protection errors in the hex 5F module WITHOUT matching DTCs in the Gateway module (i.e. the master module for CP) are in my experience, symptomatic of a hacked MIB unit. Have you connected your car to FAZIT after retrofitting the new MIB? If the MIB has been hacked- anything is possible !!
Most concerning is the EEPROM error in your screenshot above - any further information about the history of your new Discover Pro unit would be welcomed
Don

Hey guys, Need to resurrect a 2 year old thread... Don, you mention something about hacked unit errors for CP. I'm having the issue of getting map on AID display. Just shows the compass as in images above from Carolco. Backstory...I have a Golf mk7.5R that has had Dicovery nav upgraded to the Nav Pro 9.2" by a previous owner. The cockpit has also been replaced by the same owner. These were upgraded/replaced as the car had them stolen from it and the originals were removed by the thieves. I can't get the maps to show on the AID cockpit at all. Have checked coding several times. Being the 9.2, in 5F 'Ability to switch nav maps' is set to OFF as it should display in the AID and MMI. If I toggle that to ON, the MMI screen shows a button to swap to AID as it should on the standard Discovery nav however this button is greyed out with no ability to send the map to the AID. Being the mk7.5, all AID models have the ability to show the map. Is mine not doing it because of the CP errors on the hacked unit? Please help, I know it might be a little thing to others but I'd like to get the map data on the AID... Any help is much appreciated! Thanks

Not 100% sure but I think when I changed ability to switch maps to on I couldn’t get maps in the AID,

Hi vwjap,
I've tried it with the switch maps setting on and off. Only thing that changes is when on, the button on my MMI to swap to AID is greyed out.
I've checked fault codes today and found an error in 5F for 'Optical data bus - Open circuit U104900'.
It also has errors for CP and Control module software incompatible. I'm assuming these are due to the hacked nav pro unit.
Will check the optic cable and report back what I find.

Progress update... So I checked the fibre optic cable and found the connector that's supposed to go into the MMI unit broken. Got a replacement cable, wired it from the MMI to the AID. I no longer have a fault on 5F for the Optical data bus and can see the signal following through the wire to the connector on the AID side. I got excited thinking it was fixed, put everything back together, turned the key and disappointment. The issue I have now is on the AID cockpit, when I go to navigation, it just says 'Starting Map View' with a loading spinning icon. It continues to spin forever with no actual maps loading. The map on my 9.2" Nav Pro is fully loaded and functional and works just fine, just not being displayed on the cockpit. Anyone got any ideas on what could cause this to happen and if possible how to fix it? I haven't checked coding too deeply as the current coding should be correct. Thanks all

Ok so I managed to fix it finally. Once I changed and confirmed the fibre optic cable was sending data from the MMI to the AID, I still couldn't get maps to work. Read through infinite posts and forums and finally got it to work! I found a post on VWVortex with all coding required for the MMI and for the AID. Thanks to Bbusato from the US for compiling everything in one post. www.vwvortex.com/threads/active-info-display-aid-diy-retrofit-guide-for-golf-alltrack.9233891/My issue was with coding in 5F - 'Open module 5F and open Long Coding Helper; go to Byte 22 and uncheck Bit 0 - Instrument Cluster Graphics [STANDARD]'. For some reason, Bit 0 was checked. As soon as I unchecked it and rebooted the MMI, the maps loaded on MMI and AID. You have to reboot the MMI unit for any coding changes to take affect. Can be done in obdeleven or using power button on MMI or remove key and lock car for a minute. I've seen a lot of people have the 'Starting map view' error and it was always solved by an issue in the coding so if anyone has this issue, check all coding is correct using the vwvortex link. For me I had to replace the fibre optic cable and also alter one part of the code. Glad its finally working Made me happy. Thanks

Hello,
I have a problem with mine, the car suddenly stopped loading the map in the Virtual Cockpit. In other words, it only loads in Discover Media.
And the button to change the maps is visible, but it doesn't work. I'd rather have the map only in the Virtual Cockpit than in Discover Media, because I think it's more interesting that, in my case, the car gets the message in the cockpit ‘loading map view’.
Does anyone know how to solve the problem?

navigation_map_resolution: resolution_1
What does this mean? What happens if it changes?
