Indicator arrow drifts all over the map.

[Ralph Kafka]

When I start navigating, my arrow drifts around and map. It's like it has poor GPS signal but Google Maps and Waze work fine. I've tried with it offline and online and neither seems to work right.
Any idea on how to get this fixed, navigation is unusable when operating like this?

Somehow your phone seems the problem combined with how MRA the GPS data uses. Maybe even other apps are interfering with the GPS on your phone. Just guessing
In the past i've tried Calimoto a few times and had the same problem. But only with Calimoto. While other people have no problems with the GPS position in Calimoto. Never tried Calimoto anymore.
Just like you other apps didn't had this problem in my case.

Did you try using an other phone? Just to rule out causes
