I’m experiencing the same issue on iPadOS 27 on a Cellular iPad. It affects all navigation apps I’ve tested, not just Apple Maps. The map rendering itself is perfectly smooth, but the GPS/location position is unstable and updates in noticeable jumps/stutters while driving. Since the same behavior occurs across different navigation apps, it seems to be related to iPadOS/Core Location/GPS rather than a specific navigation app. I did not have this behavior before updating to iPadOS 27…
