Thanks for the response hawker...im not saying you are wrong but when i did the auto scan, at one portion of the menu I saw all the codes that were programed in, I could have sworn they were all four digit codes...but come to think of it all the first digits may have been 0...I will look again, and so now if I have a three digit code for my RCA receiver I just put a 2 in front of it...in the aux mode...isnt that four digits? or is the 2 just to signifiy aux mode? anywho,
thanks for the advice and I will give that a shot tonight.
