I drive a 2019 GLA 250 and am disappointed with the navigation system which says - as an example - 'turn right in 300 metres' with no mention of the street name. Further, a right or left turn is often referred to as 'keep right/left' instead of 'turn right/left'. My previous car had no such problems and directions were crystal clear with name of streets clearly enunciated. Before resigning myself to using google maps via apple play, would anyone know whether the Sat Nav system in the GLA 250 can be changed or updated.Many thanks
