Hey everyone, so I just got the X850BT used and got everything hooked up (except the GPS antenna and mic since they weren't included). Everything works great for the most part but the clock isn't currently displaying the time. It just reads "--:--" and when I try to adjust the clock in the main settings nothing happens when I press the + or - buttons. Anyone have any idea what could be causing this? I was thinking about trying a factory reset but I didn't want to risk needing a password or something I don't have after doing the reset. Any help is greatly appreciated. Thanks!!
