when connected to Bluetooth able to access my mobile apps and voice command (sync 3 '17). but as soon as I connect to AA through USB mobile apps and voice command go dead & blank not high lighted. (am using google maps not factory installed maps). i then have maps and everything else AM, FM,Sirius and synced apps ex Amazon Music. does anyone know how to turn on voice command and mobile apps back on in AA? . doing a lot of head scratching
