Hi, in my Range Rover L322 I have a navigator MK4 that after a few hours it goes to crash, did I think pits a problem of temperature and so' I have modified the fan so that it always ignited but have not I resolved unfortunately, I now believe that a problem of firmware and I would want to make a downgrade using the V28 for then to again install the V32 someone knows where I can find these firmware please?

thanks to all in advance.

The download for v32 is on the script below the "How to Video"

Click on "Version 32 is the latest software for BMW MKIII and MKIV"

I find a more v32, in bmw files and modified files, in the last position is "Range Rover OS - Non Touchscreen Original MODE2/FORM1" and "Range Rover OS - Non Touchscreen BMW Logo MODE2/FORM" what's correct ? for downgrade what firmware can I use ? v30, v29 or v25? at the moment I have a v32 with range rover splash but these not work well.

many thanks for support.
