I bought one, no unifying receiver included and it does not turn on.  Asked for a replacement and got the same thing.  I will just stop using either Logitech or Amazon, this is ridicules.

I too couldn't get this receiver to work either until I downloaded the most recent version of the Logitech Unifying Software from the Logitech site.  It took me through the steps of re-pairing the mouse with the receiver and now it works fine.

At first, I bought the transmitter plus the receiver, the first transmitter came out of order, it fault since the begining;wishing not to waste the receiver too, I taked the risk and I ordered another single Tx, and afortunatly this second TX works very good, but the anouncing says this is a video and audio system, the Rx has audio and video outputs, but I never found the audio input for the Tx.

Only 1 of the receiver units worked, sad thing is I didn't find out until after the return policy timeline as I only had 1 dog and didn't need to use both.  Next time - check both units and use them immediately to make sure they function properly

The ad and description clearly state that it includes both a receiver and transmitter.  I received only a receiver. This is false advertising and is patently illegal. They ought to be ashamed of themrselves.

Didn't work for me with my receiver.  May have just been an issue with my receiver and being compatible with it, but it didn't work for me.

I was looking for a receiver with "B" speakers as shown on the view of the back of this receiver. Be aware that the item shipped is not the same as pictured. The SKU pictured is 12562 94670, but the one shipped is 12562 94661. It has no "B" speakers or a SIRIUS input. A replacement had the same SKU and was refused. I was told that this would be corrected...so far it hasn't.

No where in the description of the product does it say it is for a 1 1/4" receiver not a standard 2" receiver. The photos for both look identical, so under product details, what receiver this is for would be very helpful. I just wasted my money and time buying this product as many others have also.

I've been delaying writing a 'review' of this item until I'm able to get it fully operational.

First of all, I am not a first-time user of the "ONE FOR ALL 'Kameleon' 6-Device Universal Remote Control (URC-6960)."  Some twenty-plus (20+) years ago I purchased (and paid more than $100 for) the initial generation entitled "Radio Shack 6-in-One Remote," catalogue #15-2133.  It was on the basis of my generally good experience with Radio Shack's R/C that I bought the "OFA URC-6960(B000)."

It took me quite a while to get used to the drastically revised method of initializing the URC-6960 with the TV-Monitor/BR-DVD/Cable items to be controlled  the problem, at least for me, was the disjointed, illogical manner in which the instruction book is written.  It was necessary for me to re-write each section (to eliminate much of the excessive verbiage) so that I could walk through each set of instructions without unnecessary frustration.

Still I have NOT been able to 'marry-up' the "OFA URC-6960" with my new (7/20/2012) "Yamaha AUDIO Tuner-Amplifier (Home Theatre), model HTR-4065 AV HD Receiver (5.1-ch)."  I've tried without success to get an updated listing of 'Setup Codes' for all the supported equipment, especially my 2012 Yamaha "HTR-4065 AV HD Receiver (5.1-ch)."  I wrote my first request on 12/7/2012; I'll write a second request today, this time with a copy sent directly to Amazon which I trust implicitly (almost).

I am able to pair the receiver to my Rocketfish, but there is no sound at all. I tried it on two receivers and neither worked. I called Rocketfish and the customer service rep could provide no help. It seems like this is a Best Buy product, which explains why it is useless. I am sorry that I bought this item. I suggest that you pass on this and pass on Best Buy as well.

We bought the receiver, and hooked it up to existing Panasonic speakers and a Polk sub-woofer. We use it as our surround sound system. It has worked flawlessly. I think it was a great purchase.

Didn't come with 1/4 adapter as listed package so I'm going to have to go buy one so they're useless for the moment.

I shopped AVRs for well over a year - waiting for the prices to get within my range. waiting for the best combination of features. In general, this is a good reciever with good value.

The major disappointment...I had a specific application in mind. A required feature was 2 simultaneous HDMI outputs. My exercise room is on the other side of the wall from my home theater, and I want to be able run a HDMI cable through the wall to a TV in the exercise room.

I spent most of Christmas day doing the original hookup, getting the second display set-up, drilling the hole in the wall, running the cable etc. The hookup is pretty much intutive, but when I hooked it up, it didn't work. I tried the Zone 2 functionality...still no luck. After a couple of hours reading the manual, I found fine print buried somewhere in the middle of the manual (literally, one sentence in a large manual) that explains that the second HDMI output and the Zone 2 output are only operational if the original input is analog. Most of us have replaced our analog source components with digital. What is the point of a state of the art digital receiver that requires analog input for some of its features.

I let it go for awhile, but today I called Onkyo support. The rep, a nice guy, verified that, indeed the 2nd HDMI output and the Zone 2 functionality only work when the input to the receiver is analog. He went on to say that he was very familiar with this question because he has answered it literally hundreds of times. When I complained that the literature and marketing documentation is silent on this restriction, he said, "Well, that's marketing".

Since I have spent quite a bit of time, energy and money on alternative settups and cables - analog for the Zone 2 connecting, and HDMI for the 2nd output, I am frustrated. The second TV, a receiver and speakers are sitting in my exercise room taking up space. Now I'm shopping for a HDMI splitter, but I'm skeptical that a splitter will work. I tried one a while ago in a different settup with no luck.

So, all in all, not what I thought I was getting. I'm going to call that nice guy at Onkyo back to see if he can recommend a splitter.

Update
After a couple of more calls to Onkyo, it turns out the first Tech Rep was incorrect. After I called Onkyo a couple of more times, the Reps were able to get the receiver working exactly the way I had hoped. All of my issues have been resolved, and I have changed my rating to 5 stars. The culprit was the length of the cable run - 30 feet. When I used a short cable, it worked perfectly. The Reps suggested a cable booster (aka extender) so I think I set.

I am writing this primarily to confirm to others that the K320 keyboard does pair with the M305 mouse with the unifying receiver from the keyboard. I noticed on the bottom of my M305 mouse the orange unifying logo.  Although the M305 mouse does not come with a unifying receiver, the keyboard does.  One must go to the Logitech website to get the unifying software.  For most people the latest Setpoint software (also from Logitech website) may also be helpful.  I bought this keyboard primarily to hook up the laptop with HDMI cable to the TV. I have a HP laptop and on that laptop the F4 key is used to duplicate the image to the TV or use just the TV, etc.  I was not able to figure out how to get the F4 key on the keyboard to duplicate this function.  I can workaround this by right click on the desktop, select screen resolution, then by clicking the down arrow in the multiple monitor field and selecting the display choice.  It would be absolutely great if I could get that F4 key on the keyboard to work the same as the laptop F4.  I would rate the instructions as horrible. No step by step for programming the F keys.  Actually, I don't think they can be programmed. Only the hotkeys with the Setpoint software. The Setpoint software did not provide for the same option as the F4 on the laptop.  Also, Logitech (on their website) did not list the M305 mouse as being compatible with the keyboard.  Logitech should update their their own guidelines.  I think maybe a previous generation of M305 mouse did not have the unifying logo and therefore was not compatible with this keyboard.  However, they should update to state this and clarify that it is compatible with the latest M305 mouse with that unifying logo. No complaints with the keyboard itself.  By the way, the num lock does work but there is no light as has been mentioned, but I didn't get any on screen notification either.  Just toggle the num lock and try it.

Ordered the receiver specifically for Sirius satellite radio, had it installed in my car with all the necessary wiring and the satellite receiver.  When you scroll through the input options, Sirius satellite radio never appears as an option.  You can enable IHeart Radio and Pandora in the options, but there is no such option for Sirius.  There is no way to get it to appear on the input options.  This is a factory defect since there is no way I can actually access Sirius on my receiver.  The cost of a new receiver is about the same as sending it in for warranty and the time involved in shipping and repair.

Did not come with the required antenna receiver adapter that plugs into your Garmin. Garmin Support does not know why they make these packages without telling consumer that this is just for additional cameras and not for initial camera setup. Garmin supports several cameras at once.
