Long story short I went with friends yesterday to a new location and the driver, using Google Maps on an iPhone got hopelessly lost. We switched to a different iPhone and had no problem.
The driver told me later the map did not display a circle for the destination only a blue line ending at the destination. Apparently this happens from time to time. The iPhone is a refurb from Apple. He says it is fully up to date on the OS and App side.
Any ideas on what the issue is and the solution?
