I went to bestbuy and got the harmony remote , I couldn't control my Sirius tuner that's for the receiver to change channels up and down .. It worked one way but not the other , Like sr100 and so forth .I got the harmony 650 and took it back .I was thinking all for one maybe . I found one on eBay for 85.00 bucks but that's too much when I can buy a new one for 100.00 . So Im looking for a remote that can just control the receiver and lower the volume and change the Sirius channels from the remote control too . Im going to try other brands to see if it can control the receiver .
