Hey guys, So my MIB has (finally) been upgraded to a v2 and I’m loving it - still got a few teething problems with it, but we’re getting there! The guy who did the activation/CP removal didn’t enable the MFD display - I set the value for the “Navigation/Compass” to Active and now, I get this:  It’s getting something because I get the “Loading Navigation” text on ignition, I even get the start of the route guidance if I punch in a destination, before it reverts to this. I do have a fault in the 5F for the antenna circuit being open. I bought a non-OEM antenna off Amazon for the Nav (and it works really well) which is under the dash, but I doubt that could be the problem? Is there another setting I’ve missed somewhere, or something else I have to do to enable this? Am I not right in thinking there should also be a big compass available as a display option here, or is that only for the AllTrack models? |

Curiouser and curiouser... So, I get nothing at all from the built-in nav on the MFD, until I activate navigation in AppleMaps with CarPlay?   The minute I activate the built-in nav again, it goes away... The nav itself is working perfectly, it picks up plenty satellites and the positioning is really accurate.  For expediency, here are the values from my 5F unit and my dash: 5F: 02 73 00 01 00 00 00 00 11 11 12 02 00 28 00 00 1F 02 02 E6 41 80 01 00 07 Dash: 27 AD 01 10 2F 80 26 00 01 88 6A 01 00 00 00 I think there's some kind of iPhone integration setting which is incorrect but I have no idea so that could be COMPLETELY wrong. |

hmmm.......... with the caveat that the accuracy of remote diagnostics via these forum is subject to many limitations - your description of problem does suggest an issue with the SATNAV aerial.
When you activate Applemaps with carplay- you are not using the car's SATNAV antenna - the information is being streamed to the MIB via the Iphone's antenna. This explains why the navigation is happening correctly on Iphone.
According to your long-code string, the MIB is programmed for "Europe" SATNAV (Byte 3= hex01).

I understand how it works works with CarPlay, but the built-in navigation is also working - the iPhone does not relay anything to the MFD, however the MFD only displays nav data (compass and current road) when Apple Maps is directing the vehicle.
While this is working, I get the full functionality of the Nav from the MFD. I can use the arrows on the steering wheel to select a previous or saved destination and begin calculating a route - if I do this, Apple Maps get switched off and as soon as the built-in Nav starts directing, the error on the MFD comes back.
The MIB is picking up around 12 sats using the antenna - last night it was displaying “9/11” for the entire test journey I took it on but nothing came through to the MFD from it.
That only seems to happen when CarPlay is being used for navigation, not the built-in system and it makes me think there’s a coding value either not configured or missing which is preventing it from working. Presumably the dash/MFD has its own computer (as it is it’s own control unit) and needs to be set to receive information from the MIB in order to display this correctly?

Post up 5f dashboard display configuration

The whole configuration? What’s the easiest way to get that from the app, I’m assuming the long coding data isn’t helpful?

These are the adaptions you can see easily that sends the stuff to the mfd, best place to start I’d say, you could either do a backup and email it to yourself, then copy/paste the bit I asked for, or take screenshots and post them, it’s only like 12 lines of code

Ok, here it is:
Dashboard_Display_Configuration
navigation map transmission mode
off
navigation map compression mode
RLE
navigation map resolution
resolution 1
crossroad detail map transmission mode
off
crossroad detail map compression mode
RLE
coverart
Off
stationart
Off
call picture
Off
crossroad detail map resolution
resolution 1
fastlist most
Off
ability switch nav maps
Off
dynamic icon
0
Question - can you display album art on this?! Or does that only work on the bigger, Digital dash style displays?

Dunno, I have aid, but it might show up in a colour mfd
But looking at it if RLE means just arrows then it looks ok, (I have maps in most, and compression as h264, top two)
Byte 22 seems to be the byte that does nav in dash, and guessing bit 4 (08) puts it under can bus (mines most which is fibre optic and I have bit 3 (04)) which also looks correct

So I thought it might be because the transmission mode is set to off?

So is mine
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
But you have 5 different options for that
Off
Most high
Most streaming
Lvds map fpk
Lvds map mmi dashboard
I’d say most is fibre optic
And lvds is low voltage data signaling, basically a high speed data link, don’t know what it’s used for in the Vw tho, could be nav data

Yes mate AID= active info display
I added a bit more to above post
Also thought I’d the compass activated and on the canbus?

vwjap I'm in trouble for breaking a rule by quoting your entire post each time - my bad! You'll have to excuse my ignorance - I'm an IT guy so this isn't alien to me but the terminology and architecture is all brand new. You're right - MOST is fibre-optic. At least, in my Golf, MOST is used for connection the MIB to the amplifier for the Dynaudio/Fender sound system - in Japan, it's also used to include a TV display - and the guy who did my retrofit told me that the unit I'd got my hands on supported the digital dash, if I wanted to go down that route later. I've just done some quick research - we can rule out MOST, because I don't have the LCD behind the wheel. Looking at what LVDS FPK is for (frame grabbing from the infotainment unit, via Ethernet - most likely the "infotainment recorder" specified elsewhere in the adaptations menu) I think that leaves us with the final option - MMI. Comparing my car against a 2019 plate Audi Q3 my friend drives (which as analog clocks and a digital display) I'm tempted to say that this is the one that needs enabling. My thinking for that is that Audi coined the term "MMI" for their infotainment system years before the MQB platform and MIB were introduced. My parents had an '09 Audi Q5 with HDD-based Sat Nav and a colour display in the dash - I had an '11 plate Audi A1 (no nav) and a b/w display, but it was also MMI. I wonder if this is how it's therefor referred to internally, even though VW market as "Highline". Does that make any sense at all? My ADHD may be off on a totally wrong direction with that. But it doesn't seem out of the question; the A1 was based on PQ25 platform and the Q5 was MLB. What I still don't understand though, is why I get the data from the nav unit when CarPlay is being used. This makes me wonder if the data for the nav is less "fed" from the MIB, like a "dumb" video feed for the digital dash and more "presented" somehow, to the control unit for the dash. Again, excuse the clumsy terminology for that - it's the best way I can think to convey what I mean at this particular moment. I've obviously enabled the Navigation/Compass long-coding in the Dashboard control unit. I suspect you may be correct though, the CAN bus is going to be involved in this somewhere; what else relays the data between the separate control units, if not that? Of all the units, it's probably the one I'm most apprehensive about poking around in - I have had a look however, I don't see anything which relates to the navigation in there. But my German isn't also that great so I could be missing what I'm looking for, entirely.

Mmi = multimedia interface
I’m just wondering if you have the actual lead fitted for the lvds, won’t hurt setting it to mmi tho, don’t work switch back

vwjap so I tried that yesterday but no cigar - behaviour is still the same. I would be inclined to agree with you on that, if it wasn't for the fact the compass comes upon the MFD when Apple Maps is doing the navigation. It's only when I use the built-in Nav, or it's not activated at all, that I have the problem. So it has to be one final coding bit that's missing which is stopping it or how else would it not be doing it? Wouldn't the LVDS cable also be used for getting vehicle data such as oil temp and fuel consumption to the MFD as well?

2 things, do you have a backup of your 5f from the old unit you can compare, and 2, how did you remove component protection?

Yes, I do actually - but it was a composition media system so I'm not sure how useful it will be?
I don't know how the guy did it, it was someone from a Golf forum I'm a member of who did it for me but my understanding is that he looks up the VIN of the car that my unit was originally fitted to and "buys" the FECs from that car to the unit as it's in mine? When you look in the hidden menu on the MIB, they're all there and installed correctly.
