Does anyone know how to do this? Do you need to connect your receiver to the serial port of you pc or what?
Thanks all.
while i can't answer your question, i can direct you to
their website, do a search from your model and there is a contact email to fill out. They will respond in a timely manner and can determine if your receiver quailifies for the upgrade. I've had great success contacting them with my questions. Plus, its FREE! Well, i guess you paid for it when buying the unit.
Be sure to let the board know what you find out.
