I am floored. After being frustrated for almost two years with a Kenwood VR-507 and a RC-R0720 remote, I came across this thread. So I had to try it. Tapping is the answer. I cant believe it works! Im going to submit this thread to Kenwood. I emailed them about the problem about a year ago or more and they told me to reset the reciever and change the batteries in the remote. I wanted to punch the guy that responed to that. Anyway, maybe they'll look into it? Ill also cc the better business bureau to the link. If nothing else, maybe it will get someone to look at it.
