Enable 2D maps on pre-LCI E60

[neo_andersson]

Hi, I am new to this forum and i don't have an X5 but i see you guys are the best in terms of BMW navigation. I hope you can help me with this issue.

I have a 5 Series saloon (e60) manufactured on 02/2007 , a pre-LCI.
The car has factory fitted Business Nav which at the time had only ARROW VIEW. I saw that the LCI 5 series manufactured after march 2007 has 2D map display as standard for Business NAV.

My question is: Can i upgrade somehow my nav system in order to enable the 2D map display?

I have to mention that i checked with my dealer and he has no idea if this is posible or not. I was the first one to ask them.

Any help is highly appreciated.

Thank You!
