Occasionally I'll rent a car that only has Apple's Car Play and have to use my work iPhone to navigate (gawd forbid Apple would let us use Google Maps on Car Play;).
My experience has been universally poor:
- it provides no instructions for major actual intersections. It thinks you're staying on same main road even when there's a confusing Y in front of the driver. I have constant moments of panic when I see the intersection coming and no help from the maps.
- It provides confusing instructions on straight roads ("Turn right in 100 meters" when there's a stretch of straight road)
- It'll reference names for a road that are nowhere near what any of the signs indicate
- "Keep in right three lanes to stay on the road" - when the rightmost lane is actually a turning lane
- Something that is admittedly tricky, it struggles to provide useful instructions on more than four-way roads (e.g. if it's a 5-way or 6-way, "Turn right" has multiple interpretations). It doesn't use, at least not in my cases "bear right" or "slight right" or similar vs "turn right" or "acute right" or "sharp right" - and again, it gets the road names wrong.
- When Searching:
* it'll show me Bedford England 5000km away, but not Bedford NS 12km away
* It has some weird internal naming so searching for actual address will again not lead me anywhere near to what I want
Basically it's been a constant source of frustration beyond what I believe could reasonably be attributed to my inexperience with its UI :-/
EDIT/UPDATE: Thx for feedback; my work phone is on iOS 11, good to know that (*recently, after 4 years without it) CarPlay now supports other maps; note that I don't think it in any way makes Apple Maps experience itself any better 0:-)
