They stop using GPS recievers, therefore nothing for GPS to connect to.
Its a slow transition, but it is one of magnitude. The US could shut down the satilites over Iran, like Starlink did it with Russia/Ukraine.
They are preparing for that, and mostly for the US to loose the power to potentially do it. It matters in case of all out war.

It’s stupid to not just use all the available systems. Don’t just support Beidou. Use Beidou, Galileo (European), GLONASS (Russia) and GPS. Makes lock on faster, increases precision and helps if one doesn’t work for whatever reason.
The US cannot just shutdown Iran’s usage. That would impact all other countries as well. GPS consists of only about 30 satellites for the whole world. Starlink satellites are much much lower and can thus be more easily associated with one country.

Echoing this, civilian GNSS is a passive system, and I’m all for redundancy, you should be using all four constellations for the highest accuracy and fastest lock.

Yes, you should use it for the fastest lock, but if your interest is to keep the US out of influence, ofc they would do it.
Either that, or they do it to please China hoping for an ally. Second option might be their played hand, even if it doesnt work.
