If you buy one used that is how you can get around giving Google money.

From a security standpoint it might give you a temporary benefit since all of Google’s tracking IDs will be associated with the original owner. On a new phone I figure it’s associated with you immediately.

For my truck, I ended up looking in the owners manual and found a fuse that is for the modem. I removed it and the vehicle functions without issue.

I know it works because when I brought it to the dealership to get serviced they said they couldn’t connect to it via their online service app. They also asked if I had tried to connect to it via the company app on my phone. I just told them I never needed to.

Just to be sure I verified they didn’t reinstall the fuse and they had not.
