Hi,
I recently purchased a used vehicle,I went to use the navigation and got directed to the calibration screen. After the step I received "error, failed to save touch" followed by "cannot find nngnavi,(or one of its components) Make sure the path and filename are correct and all the required libraries are available ". On the actual unit it has a slot for the SD card but it's missing, so I assume the previous owner removed it. Could someone please assist me with on where to get the software so I can put it on an SD card? The unit is a CS‑GM1210‑US, Car Show by Rosen running the Windows
Thanks in advance
