I have (3) TIU's and I am considering selling (2) of the TIU's now and replacing them with (1) latest & greatest verision TIU unit, that has the USB port and all of the newest upgrades. Then selling the 3rd TIU’s after Christmas (when we take our Christmas layout apart) and replacing it with another new unit. But I am wondering .......
When it will be out, or is it out already?
How do I tell them apart?
I also have (2) AIU's but I don't think those ever changed?
I don't want to drag my feet and miss out.
