Hi, I'm sorry about being a newbie again, but my job has taken me out of the country for the last couple years. I'm only home for a month, before I go back to Afghanistan. Anways, I live in the Huntsville, Al area, where there is a DirecTV customer service center, and have acquired my receivers as owned. I have the opportunity to buy an owned Genie. I do not have a Swm system. What I do have hooked up at the moment is 2 r15's, and 2 HD Dvr's. What would I need to add the genie to my account? Is it even possible with the R15's? thanks again, sorry if this question has been asked repeatedly, but my time is extremely limited, and I don't have time to read multiple threads to find the answer.
