Cheap Windows CE navigation, probably from 2011.
It seems to be identical to ATD GP-318B.
Mstar MSW8324
Optional FM radio or FM transmitter?
Device hard problems with powering on and later could not power on at all.
I've loaded firmware from https://www.elektroda.pl/rtvforum/viewtopic.php?p=14928170#14928170
It seems to work, although this it Chinese version of Windows CE and I'm not entirely sure if display is working as it should (picture is terrible).
Some software (no navigation though):
