Just a couple of questions:
What do you mean by 'upload local map for proper navigation'? Are you referring to uploading a route to your device?
If not, can you please further explain?
To use the Navigation function of the device, it has the ability to see the Map and Compass, create a route and follow it, save waypoints and find them, and start at the beginning of the track.
As for this statement below:
Also GPS shows your position with "error" that points to outside of road and when 2 roads close to each other and GPS shows you in between which one is the one?
I'm not sure what you mean by this. What kind of error are you getting? Can you please provide some screenshots about this error?
Yes, the Create a Route function is not available with the Training Gym Pro. However, this suggestion has been forwarded to our engineers.
To find a Waypoint, you can go to Main Menu > Navigation > Find Waypoint. Apparently, what it does is that it leads you basically straight to the waypoint.
If you prefer detailed map (with names, labels, diagrams, etc.), then, that would require a firmware modification. Would this be your suggestion for this product? Please advise.
