*Make a copy of all original files*
First - Download Binary xml converter from here:
Binary xml converter.zip
Second - Copy Binary xml files into the cars folder you want to edit. I'm going to use fe0, which is Ferrari.
Third - Open Command Prompt (by typing cmd from Start menu then search) and have it read to the path of the cars folder that cameras is located in. In this case that is:
C:\Program Files (x86)\Steam\steamapps\common\f1 2010\cars\fe0
At Command Prompt. Copy the file path and then in command prompt right-click and press paste. Don't forget to put (cd) before the path.
C:\Users\Chad(This will be your computer name)>cd C:\Program Files (x86)\Steam\steamapps\common\f1 2010\cars\fe0
(Then press enter)
It should look like this:
Fourth - Now to convert to a readable file.
Copy this: binXML.exe --textxml=cameras.txt.xml cameras.xml
Right click at the cmd screen and select paste.
Press Enter and you should see a cameras.txt file in C:\Program Files (x86)\Steam\steamapps\common\f1 2010\cars\fe0
Leave cmd open, you will need it later.
Right click cameras.txt and open in Notepad or Word.
To edit the cockpit view press F3 for search.
In search box type head-cam and press enter.
It will be the first line. It should read:
<View type="Head" ident="head-cam" reverseCamera="head-cam_reverse" hidden="false" spectator="false" renderParticlesBeforeGrass="false" transitionType="switch" transitionSpeed="0.0000" transitionStrength="0.0000">
Now move down two line and you will see: <Parameter name="fov" type="scalar"
value="25.0000" />
Bolded number will be different for you. I have already edited mine. To change your FOV just edit the bolded line. I like 25.0000 better.
When done, File > Save.
Fifth - Convert back to Binary.
Go into cmd again so it reads: C:\Program Files (x86)\Steam\steamapps\common\f1 2010\cars\fe0
Like it did before.
Copy and paste this to cmd
binXML.exe --binxml=cameras.xml cameras.txt.xml
Press enter and you are done.
Here is what 30.0000 looks like.
Here is gameplay with 25.0000.
Here was default FOV, big difference.
