As for the RD45 - I think you recently upgraded this from and RD4 if memory serves.
This fault can occur when such an upgrade has been undertaken on a vehicle that didn't have it originally - and is either down to one of the configuration options in the BSI / Head Unit (any changes made in BSI or Head Unit ECUs will auto update each other) which may have been from a different vehicle and are not compatible with the current vehicle, or may be an incompatible software level in either the Head Unit or the MFD if that was also changed.
I don't have your VIN, but if you can take some screenshots of each page of the BSI configuration pages (best option as not all options will be in the Head Unit or MFD sections), I can go through the options as they relate to your vehicle against what is recorded in your current BSI configuration and see if there are any obvious differences.
Until that is done there will likely be some errors accessing certain functions of the unit I suspect:
