Thank you Jerry and Oleg.
I followed the guide and made it work with your help. I got 3D and all the data correctly.
Only problem I found is that, if I move to another menu on the radio, when I come back to the GPS menu function, all data acquired is gone.
Unable to make it work again.
It may have to do with what you said of Linux. So I still have to do the last step on your instructions. Write down, update manually, etc.
Will revert with an update later.
For the time being, initially it works but need to test more.
