When I got the car, 2 days ago, I put in a destination and it worked, however I noticed that it was set to british english. I changed it to US Engilsh and british english accent. Then today I put in a destination and the voice didn't work. It wanted to work, meaning that the radio lowered when the voice guidance should've told me to turn, but nothing came out. I looked online and saw some people saying that they changed the language to english US, which is what I did, originally, but now it was british again. I changedit back and the voice guidance came back. put in another destination and no voice, change the language and back to english and it works. Any idea what's going on?
