I have two TIU's and two DCS remotes - all with version 3.1 - all components are around 10+ years old by now I believe. They do not have USB ports so I cannot connect them to my labtop (which only has USB ports). I asked two of the closest dealers (both are MTH authorized repair centers) and neither one knew how to do this!? How do I upgrade the components? Do I have to send them to MTH? This all seems silly. All I want to do is to active the quilling whistle effect of my first PS3.0 engine. I am sure there are other useful features as well.
Thanks.
