Because of space constraints I have now bought a BC6-23 to replace a BC6-26. But I might not have done enough research beforehand as the BC6-23 does not have the ability to assign other sources than "PC" to the DVI connector and also no possibilities for PUC for the DVI connection. This is functionality I have on my BC6-26 and would like to have it for the BC6-23 also to be able to integrate an Apple TV. The BC6-23 is a type 9212, with software 8.6 My question is: Is it possible to update the software for this type number to gain the functionality described above? Looking at some older threads I can see that type numbers 9219-9226 should be able to get software 10.10A  where a HD upgrade kit is mentioned, but not sure if that is needed to get the functionality I am after.
