So I paired my Samsung Galaxy S6 with my Pioneer AVH 4100 NEX. Android Auto works fine, and the Android Auto address book reflects what is in my Contacts app on the phone. But when I look at the native Pioneer address book, it's got a much larger list, including what appears to be collected email addresses from my gmail account. I use Outlook for my Android gmail client - I've removed Outlook completely from the phone, re-paired the phone, re-downloaded the address book, and still get the same list. Any idea what is going on?
