Probably none of them, at least without removing the radio and updating firmware via USB or some other interface. I've never heard of a radio sold in the US that has that capability built in. The tuner chips may support it, but if a tree falls in the forest....Are all the chips programmable in every make and model of car, or just some of them? The big question is whether doing that involves removing the radio module from the car, or whether it can be done by just plugging a device into the car's electronic system and sending an update.
