Hi, Just wondering if there exist updates for the Audio/Sat Nav system for 2013 Corolla. For example, I cannot seem to get SMS messages appear on the unit and just wondering if there would be an update to fix this (unless I am doing something wrong and is not compatible with iPhone). Also if anyone knows if there exists updates to the Sat Nav side of it, the iGo version 9 as I cannot find any reference to it on my internet searching. Thanks.
