In January I replaced my 2011 Volt with a new 2014. Overall I'm delighted with the electronic enhancements. However, I can't seem to make the navigation system download addresses from my iPhone to the car. When I touch Destination and select phone book all of my contacts are there, but the car tells me that there's no valid address. All of the addresses are there and work fine with RemoteLink. Does anyone know why I'm having this problem? By the way I use Exchange for my Contacts.
