With your current tuner count, you don't need a SWiM-16, and if you drop the HR23 for a HR34, even with the additional tuners, you still don't need the -16, since you only have 8 tuners.
I am wanting to make the jump but had a few questions I wanted to clear up first.
I currently have
Swm 16 System
Can I just replace the HR23-700 with the Genie and the other HD boxes still work with the Genie as far as whole home? I am a little in the dark as to what boxes will work with Genie and which wont. Directv site made it sound like only newer boxes will communicate with it over whole home setups.
Other question is what monthly fees come along with the Genie other than the 8.00 advanced reciever fee and 3.00 whole home fee I pay now? 8.00 fee is included in my base package and I pay for three additional tv's as one is also included in the package.
Just trying to educate myself on the Genie setup but a search gives me hundreds of topics all over the place none really answering my questions.
Thanks in Advance
If you have DECA and MRV now, there isn't anything you need to swap the 34 for the 23. Deactivate the 23 and replace it with the 34. There should be no change in your bill and everything will work as it does now.
