I am having issues with navigation which is not showing maps and it stays off road all the time. Any solution?

 

Have you tried to disconnect the battery to reboot?

 

Yes, before a month or two I replaced it with a new one but nothing changed.

 

This may fix the issue. Not sure if you can change this particular setting using "Engineering Mode" or not. Give it a shot.

Under Comand "HU_Parameter" make sure "Wheel Impulse source" is set to: CHASSIS_R3

 

Tried but still the same..

 

MAybe you need new maps as the one you have has no idea where you are.

 

There's nothing wrong with your navi. The road you are on is not mapped because it is not a main road. Most eastern EU has partial coverage meaning only major roads and highways will be shown. Everything else is considered off-roading by the navi system. Go to that 1 highway that's shown on your map and you'll see what I mean.

 

A friend of mine has the same car same year but his navigation works well. That navi image is from the main road of the capital city..

 

Get it scanned and see what pops up. I have not seen or heard of an NTG4/4.5 behaving like this.

 

Can anyone tell me where i can download/buy firmware and maps online?
