Issue with odometer

I have added gt06 its sending the data with 0 lat long for few minutes suddenly it's started sending lat long, but suddenly odometer is increased lots of. Is there any configuration for fixing this??

There are options you can try. What information have you found so far? What forum threads have you read?

I have searched about 0 lat long issue but not find any topic in formu that can I understand. If there is any exit solution in forums so please share the link.

I don't have a link, but this has been discussed many times before.
