When voice control initially came to ICTP updates the Maps update was critical to ensuring voice was functional. If this is a feature you use I would recommend keeping up with updates under the assumption that Jaguar/HERE make continued improvements in this area. I personally use this less since I received the update enabling CarPlay.I feel like the last map update I did was fairly recent. Assuming you're not in, or will be a newly developed area, would there be any reason to do every update? Does anyone know if the map updates change anything else ( e.g. functionality)?
