Hi, I don't know if this is a phone issue, or a car issue . I have a 2013 VW Jetta Sportwagon and a Galaxy S4 Periodically I get a pop up on my touchscreen and/or my MFI that says something like "incomplete phonebook or contacts download" or "Phone Book not downloaded" Anyone know what might be up with that? I was told in a VW forum that I had to approve my phone downloading the contacts. The thing is, it doesn't ask. (At least when I am looking a minute or so after I start the car) I might get that popup after I've been driving for 20 minutes, I can't fiddle with the phone then!
