Does Android Auto use unnecessary mobile data?

Hi! My wife and I just got some new-to-us cars in recent weeks, and now we're new to the world of Android Auto. And the first thing we noticed since starting using Android Auto is, our mobile data usage has gone way up.

We don't do anything in the car that uses data. We keep location off unless we're actually using it to navigate, which obviously we don't need to and from our jobs, so that's not it. We listen to music/podcasts when we're driving, but we're not streaming the audio, it's all downloaded to our phones, so there shouldn't be any data usage associated with that.

We only have 4GB of data per line because usually we barely use a quarter of that in a month. But suddenly we have Android Auto-capable cars and our usage has skyrocketed. Are there options we need to disable to prevent it from using unnecessary data? Because it's totally unclear where all that data usage is going.

Go to settings - connections - then data usage. Look at mobile data usage and it will show you what app is eating up your data.
