I have been trying to upload to my BMW Nav 5 a file that has a 7 day loop of Sardinia. I have many many attempts. I have deleted old map files from the Nav, checked available space and charged the battery. I have an extra SD card with about 32G installed in the Nav 5 with lots of space. I split the route into 7 individual days and all of the 7 day routes uploaded with out issue. The complete master will not upload. Before I split the route I checked it on a Here Map through animation and all of the 50 Way and Via points are on the route. Is it too large or does it have too many way and via points? I keep getting the message “Completed. The Route is exported to your device”. The time line is very short, much shorter than the one day exports. When I open my Nav I get this message “Cannot Save GRAND TOUR OLBIA MASTER”.
Your comments are welcome.
