where is contact permissions found?The first thing to look at is making sure the permissions for Android Auto are set correctly. One of the permissions to allow it access to your contacts. It is a question you had to answer at one point because the default for any permission is 'off'
Go to permissions under set up. "Contact permissions", "Android Auto" and make sure it is set to on.
Ok, that's all I got. Perhaps visit the dealer. I'm sure it is some sort of setting they deal with on a daily basis.My phone is on under permissions
