Well, i received the receivers yesterday, but they didn't seem to contain any TMC hardware unfortunately. So i ended up buying an official receiver today (for a pretty good price). Here are my findings:
Setting is still the same: Tomtom One v1 with Navcore 9.500. I did experiment with different emulations though.
I connected the TMC receiver within the Rider 5 emulation. Here it says: "accessory not supported". This also goes for the rider 1, 2 and 3 emulations (ID's 5 and 17).
I also tested the "Self emulation" (no idea what kind of a device this is supposed to represent? A Tomtom One v1 with a Navcore 9.500 touch)? Here it gives the same error, "Accessory not supported".
It gets interesting when i use the X30 emulation though. I also have this emulation on the device because it seems to have quite some additional features that other emulations don't have and at the same time, still runs stable and smooth on the One.
When i connect the TMC receiver in X30 emulation, the receiver is recognised, the traffic bar shows up. After a few minutes, the dot turns green and all seems to work smoothly and well. This is again on the 9.500 Navcore!
So it seems the 9.500 Navcore works with TMC, the emulation gives problems, depending on if the "device" supports TMC or not. I am asking myself. Why isn't it working on other emulations? The menu structure and buildup up of the different devices all seem the same. Should it really be (easily) possible to add TMC to the Rider 5 emulation? I honestly don't know what the difference between the Tomtom's are except for a different menu structure and buildup (software wise).
Would the receiver be recognised if you add the "traffic" menu structure? Maybe i'm thinking to easy about this, but the base (Navcore) is the same for the different emulations, so to me it seems like it comes down to the enabled menu options within the emulation?
