Traxx, I realize that it "comes with" the puck, but you can also just purchase the module only. I am not sure of what the module price is, but I am betting it would be cheaper than the upgrade package price.
TR6, that is interesting. Would there be any way to find out that info using a computer to "hack" the puck? I know there is a USB version that works with a GPS program for a computer, like MS streets and trips. Pretty sure PP would not be too willing to pass the info along.
I do understand PP wanting the upcharge for getting the puck and modifying the connector, as I am sure they do that all in house. Is it worth the $200? For now, I guess so, until someone else figures out a better way.
