Tris,

I just set up my 3000 with an LS28 which is the same base unit as the LS35. I had no problems; you do need to follow the advice of all the previous repliers. Set the base unit to send and receive IR and then set the AV3000 to learn. When you press the button you want to learn make sure you have the Bose remote in the other hand and press the button you want learned once or twice. The little light on the bottom right of the bose unit will light up and make sure the AV3000 is directly in front of the unit. About 2-4 inches and just slightly left of dead center seems to work the best. I had no problems with any of the functions. Good luck
