Dear members,
Thanks for the contribution, i did take a look at this gps item, my phone has a very good gps reception, during recalculation i did take a look at the gps receipt within nextgen, receipt is very good and it is stable.

So, till now i can not see how this could be a casual factor !; I also do not see how it is related to long distances.

I would still like to solve it, I noticed when i plan a route to other countries than Hungary/Romania, it is more stable.

greetings
fiesta
