Siri integration into Apple CarPlay is so poor it is almost unusable. I had a family emergency, was observing Apple Maps on my CarPlay console with my current location, asked for a specific hospital I need to get to, and was told by Siri multiple times: "I am sorry, but I can't determine your current location". In desperation I brought up Google Assistant on my iPhone and navigated to the hospital using voice from Google Maps. I've loved my iPhone over the years (iPhone 6) but I can't trust the Apple eco-system any longer - its quality stinks! My next phone is an Android.
I've never been to Canada, much less heard of St Jerome Quebec,with my eyes fixated on the road , Google Map took me turn by turn by turn with warning to keep right or left at the fork, to my destination, not a miss.
