Good night
I'm using google translator then hopefully get me (laughs)
I'm having the same problem, I have a GO730 and installed navcore that you posted that is very good.
Except that when I connect to tomtom home it asks to update the navcore.
I changed the numbers on lines 9 and 10 as you described but it does not generate the file ttgo.ori.
My case has solution? My equipment is a GO 730 with map Brazil_895_4438.
The tomtom home application asks to update for 9430
I thank you.
