This may not be directly linked, but, I have brought my new NX car in several times for voice activated navigation glitches. To be frank it only ever worked once. I asked it to be taken ‘home’ after manually inputting & saving the address. Every other request, even with meticulously careful annunciation of destination has failed. The system tells me the addresses are unknown or curtly cancels/closes the instruction. The latest news is another update is to be applied at a date to be confirmed. I wouldn’t usually bother but it seemed to take a while to get Lexus to confirm the system was working ‘intermittently.’ Is this a common experience?
