Thanks for the quick reply cleatus12r, thats what I was figuring would be the outcome. So what would it cost to upgrade him to a DPC-422 I haven't really seen these for sale and where is the best place to find one? Would it be a pull his old PCM out and just plug the new one in kind of deal or would there be more involved in a changing of the PCM's to get everything to work out? Thanks for the help.
