Hey, I'm on TWC using a 4250HDC. I just set it up today and it works ok I guess, but the problem is, it isnt running the "Navigator" software, it is running SARA. I am wondering if there is anyway to update to Navigator without swapping my box, keep in mind I've only had this box set up for a few hours, so I don't know if it would take overnight to do any sort of firmware update to the cable box, I don't really know how that works. Can anyone shed some light on this? SARA is ok but looks like crap compared to Navigator and on an HD-TV it looks a little too outdated, plus I would like to utilize some of the new features that Navigator has. Any suggestions?
