I installed my shifter today and according to my TV remote, it is shifting. The display on the GX65 tells me shifting front, or rear head, so that part is working. When the unit turns on and goes through the self test, the book says the RD shoulld confirm ZR4 and what mode it is set to(receive only, off, or shift). It does not say anything about laser, let alone anything about the ZR4. I cannot change the programing of the shifter either, it is set to shift (defalt). All the RD lets me do is turn the laser function on or off. I also have the ZR4 control display installed as well. It does not change these issues whether it is turned on or off. Is there something wrong, or is this normal.
