Sony GPS Module and iPhone Accuracy

If I have a Sony stereo with the NV400 GPS module, does it only work with the built-in TomTom app, or will it also increase the accuracy of iPhone GPS? I have an Alpine unit in another car, and it will do this.

    Hi @manicslothpdx

    Welcome to the community!

    What exactly do you mean by "increase the accuracy of iPhone GPS"?

    For example, the Alpine ILX-207 has an external GPS antenna just like the XA-NV400. When an iPhone is connected to the Alpine head unit, it is able to use this external GPS antenna to increase the GPS accuracy of any application on the iPhone that uses GPS. I am wondering if the XA-NV400 offers the same functionality. Would a map app on an iPhone benefit from the external GPS antenna when the iPhone is connected to a Sony head unit with the XA-NV400 module?
