I think that Garmin needs to disable this feature in the 1030 software. I was surpried to see how easy is to play with Shimano Di2 settings when using it with Shimano EW-WU111 . Cool to me to have some info of my Di2 in my Garmin, but I don't want to make someone's near to me (maybe during a GF starting line) to play with my gear settings.

Hope to see some official Garmin answer

It wouldn't take much to require the unit to be in ANT+ pairing mode just like for BT. Just hold the button on the controller and then ANT+ can pair.

A simple fix is to have a manual paring mode, that require an initial pin, to fix this.

This should be a Shimano issue if you ask me. The DI2 is the one screaming "LOOK AT ME! I AM HERE!" and the Edge head units just bring the wine to the party.

I think that is ANT+ protocol weakness (multicast) which is different than Bluetooth where you have to pair with the source. When it's paired then it is one-to-one access. The only thing I think Shimano needs to improve is implement the authorization procedure of the ownership when ANT+ protocol in use.

Shimano does not use ANT+, but rather uses a private ANT implementation.

The only setting that can be changed over the private ANT implementation is the shifting mode. All other changes have to be done over Bluetooth or via the PC application.

If someone tried to change the shifting mode you would end with dueling head units. The value would be switching back and forth while both units competed. As soon as the rider got out of range of the competing head unit (approximately 30 feet) the system would get set to the value on their head unit and remain that way.

So it is possible that some one could try and mess with the shifting mode, but unless they are riding in the pack the impact would be limited to a small range near the start and would not be permanent.
