This may seem odd? I just bought the AVIC_Z110BT to replace a BOSS 9386 that has issues. I am not interested in bluetooth could care less no cell phone. All I am interested in is navigation and it does not have to be the latest and greatest semi accurate is fine. Voice activation is okay but not a got to have it. As long as I can use USB for thumbdrives or an SD card for music I am good. Any suggestions??
