I've had the 8810w for a couple of weeks now and something has been bugging me in the manual. IT says that i fyou have a new device that isn't supported to call the company and they will search their database and provide a new code for the device. This sounds like nothing more than using advanced codes? I am I on the right track with this? Or is 8810w upgradeable via a modem or sound file? My understanding is isn't but could be wrong.
