It don't work that way. We can't swap a HR24 for a HR34. That would be way different! We can only swap a "like" receiver for instance a HD for an HD or a HDDVR for a HDDVR. Model numbers don't matter but with the 34 it does.
hmm I guess the contractor got his ass handed to him then, not my problem, he got two boxes of single, a case of fittings and a few bags of screw clips out of the deal so maybe he figured it was worth getting yelled at? idk, but I guess I should be happy. Now I just need to find a contractor locally to trade me remotes and switches and stuff lol.
