You have a version 4, 5, or 6. Take the expansion bay cover off and look at the top rim, if it has 2 screws it is a version 4, if it has 3 it is a version 5 or 6. I am not sure what the cutoff point for having an up to date dvd driver. Question, is it that your remote does not work at all, or just some functions don't work? If it doesn't work at all then the update won't help, get a new remote. Otherwise, I would try to contact sony and see if they could send you a copy of the dvd upgrade disc.
