how to upgrade the NAV600 to a NAV900.

[mitodabadee]

I recently did the NAVI 600 - 900 upgrade in my 2012MY Insignia (with 2012 map SD card), everything works perfectly but there is no option anywhere for the 3D map view. The other NAVI 900 options are there such as tour mode for multiple destinations and POI alerts.

I followed everything in the instructions to a tee and the only problems I had was with the correct file not being burned on the discs, which the system rejected and after the correct one was put in it accepted it fine. Another thing is that I used a 16GB USB instead of the 8 which the instructions recommended, however it was formatted correctly.

Does anyone have any ideas as to what I could try to get the 3D map? Help would be greatly appreciated.

Thanks in advance
