F900BT - Can i change the FM Frequencies available

[carbonr]

I live in Dubai (Middle East) and had my car imported from the US and it came with the F900BT and found it reasonably satisfying all my needs except with FM and Navigation.

 

I have two questions:

 

Question 1:

The FM Frequencies available are in odd number like 100.1, 100.3, 100.5, 100.7, 100.9 etc but  here in Dubai we have stations on all frequencies like 100.1, 100.4, 100.5 etc (even number also)

 

I'm wondering if there is anyway to make it work with even number, maybe installing the european firmware or something like this. 

 

Question 2:

The same question stands for maps. I have Middle East maps from all major providers like TomTom, iGO etc but is it possible for me to load it on this device.
