GPS accuracy issues on iPhone 16 Pro Max
We have had a hardware test at an apple store and everything is apparently fine. Reset phone (iphone 16 pro max on iOS 18), also deleted and reloaded GPS apps. We stopped using carplay although no change to carplay softare (if that is even possible). GPS is inacurate and often displays that I am on another, incorrect road and suggests turn that do not exist on the road I am on. This is consistently a problem regardless of the vehicle I am in. I get a messages that GPS signal is has a problem - therefore the system is using an approximate location. I will try removing the rather simple, clear cover and any magnetic attachment to the back of the phone. Some suggest turning off bluetooth, toggling airplane mode etc, but many users attempting myriad options is not improving the situation. Surely apple service people are having this problem as well? A second 16 pro max, purchased via AT&T at the same time, does not appear to have the problem.
I have spent more than 1.5 hours on the phone with a very helpful apple customer service person and 45 minutes with a tech in an apple store (who had no idea that this is a fairly prevalent issue). There seems to be no acknowledgement of this issue by Apple to date, let alone recommendations for a fix or any official response that I have seen.
