After seeing all the posts about not being able to update the main firmware version to V1.06, and the indifference from Onkyo customer service and the service centers, I posted the following to Onkyo customer support. I have learned so much in the last week from the SR-705 Owners thread, and have a lot more to digest. It's a shame Onkyo is not giving it's' customers a straight answer about the Main FW updates.
I am a member of avsforum.com, used the SR-705 owners thread to help in setting up my reciever. I found DSP's update and sucessfully downloaded to receiver. Am seeing a large number of posts on Firmware updates to V1.06 (Current V1.01) not being available ,and Onkyo customer support and Onkyo Service centers refusing to give any info about firmware versions. Seems there is a benefit to the operation of my SR-705 and I would like my receiver updated to the latest Main Firmware version. Thanks for your help.
