I have navlink DVD GPS system (made by "joyous" in china) and it says navi not exist,i cant even get to setup so can any one help, all i can get to is DVD TV radio etc,when i press on navi it says navi not exist,i have tried resetting bit to no avail, i even left the battery disconnected overnight to drain the internal memory but still no access to the nav settings.
This took me weeks to solve because they dont give you a decent manual. It is necessary to have a good map on your sd card. You have to go into your map setup software and tell it which serial port and baud rate to use. otherwise it will display as you state.
