Teyes head unit is a step above the rest for features, however tech support can have an attitude and be persnickety about questions unless it pertaining to navigation. How dare you ask about anything regarding any other features!
the music production is fantastic. it is very user friendly. But item arrived so late - probably because of COVID 19. Its a good thing to have chosen this product. it came with Russian language, but with seller's back end support I shall as able to change it to English language.
