One exception I am using external Garmin marine antenna on car root for reduction of correlation with directivity pattern. In this case tracks is equal without difference - go forward or go back.
no I dont try because I Dont care about accuracy so much on my nuvi , but I care on my etrex , and 2-3 meter its what I got on etrex legend HCX
