GPS coordinates?

Hello,

'Does anyone know whether the position coordinates from the MFD (Multi-Function Display) are transmitted via the Comfort-CAN or the Navigation-CAN? If so, I might be able to avoid connecting a GPS mouse to my carputer. As far as I recall, the number of available satellites is provided via the Navigation-CAN. It's possible that the coordinates are also included in that data stream.'

Regards,
Axel.

As far as I know, the GPS data is only sent to the CAN bus if the Audi Log Book is installed/registered (since this is the only device that would process GPS data).

That would be stupid . I'll debug something again tonight. Otherwise, I'll flash the Navi+ firmware onto my MFD and add the electronic logbook functionality to it. Unfortunately, VW never offered this addon :/

Well, look at that, it's Axel .

'What's the problem now? The navigation computer is connected to the head unit internally via CAN bus, and according to my information, everything goes through it. By the way, even the firmware update happens via CAN. The CAN connection is located at the rear of the Siemens connector...'

Best regards,
Sven.

Hi Sven .

Okay, I thought so. Unfortunately, right now I'm only able to work on debugging the comfort CAN bus, and the amount of data available there is rather limited :/ I'll be focusing on the navigation CAN bus again on Monday.

Axel.

Hi Sven,

And? A lot of time has passed , what results have you achieved?
Hast du mehr Details, was wir alles auf dem Navi-Can finden?

Best regards,
Andreas

I wanna say hi for everybody. I'm new to this place.

I think it might be related to ID 0x5A3 on the infotainment bus.
id:5A3 len:8 msg:10EA22330C0EF70F
It should point to the Auchan Bielany petrol station near Wrocław .
Sure, I can help you translate that into the "ddd° mm' ss.s"" format. Please provide the text you would like me to translate.

Thanks Sir! It works!

I'd like to add to this old thread again. For an Audi S5, B8, I think I once had the data for the GPS position, but somehow I've lost it. Unfortunately, "5a3" isn't sending anything on my system, so it must be something else. I can't directly filter by byte because the coordinates probably aren't stored as an 8-bit field (as I can see from the formula in the post above).

Does anyone here have a suggestion on how I can search further? I've already tried sniffing, and I even have a short log with the exact location.

Greetings,
Rolf.
