Not had the model you mention had a similar Chinese sat nav. Would advise getting a screen cover, bit like a hood that fits around the screen of the sat nav as the brightness is not it,s best feature. They are a bit delicate compared to mainstream sat navs. (Dropped mine, RIP sat nav) but as far as navigation went it was okay, no problems really, did have a hissy fit and lock up now and then but no more than any other sat navs I have owned.
