MGM Programming Question

[Sower]

Hey guys - I have a question about programming my MGM. Big surprise, eh? Well, I got the 160 from Mike this last week and have done a preliminary transmitter programming thanks to Jhautz and a few others posts. The problem is that I pait $30 for that USB connector and it's not doing a dang thing! Do I NEED to have that other $10 patch cord that is out of stock right now or can I do it w/o it? I would really like to customize everything and make sure I did the settings correct. Any help is great - thanks.
