I got the free 54.0 remote yesterday and it works ok on my H2 so far, but I haven't gotten the latest update though. Overall, I can't say I'm impressed with the 54.0 over our 40.0's, so it will likely get tucked away as a spare.
I posted earlier about needing to contact Dish to get the remote shipped to my billing address instead of my RV park service address, which I did. The CSR was very cooperative and spent quite awhile getting the order straightened out and headed in the right direction despite the computer system repeatedly trying to send it to my service address. Then I ended up getting two confirmations, one for each address! Then yesterday I got two "Out for delivery" notices, one from UPS for our billing address, and one from the USPS for our service address. Since we're no longer at the service address location, I called the park and told them what was coming and that they could give it anyone they new with a Dish system, keep it themselves as a paper weight (they have cable), or refuse the delivery. The owner thanked me and said her daughter has Dish, so it'll go to a good home anyway...
