Voyager to Prodigy Brake Control

When we bought our TM 6 months ago, the dealer installed a Tekonsha Voyager brake control in our TV. So far, it has workd fine. I have used the manual on how to adjust it, etc. If you have a Voyager, you need to read and follow the manual.

There has been some positive comments, on this board, about the Tekonsha Prodigy brake control.

If you have changed from the Voyager to the Prodigy, what do you consider the main benefits of the Prodigy over the Voyager?

Since the prodigy can be bought for just under $100 (the price is right), is it worth it to change over to the Prodigy?

How difficult is it to change from a Voyager to a Prodigy?

Since they are both made by the same company, can the wiring harness for the Voyager be used for the Prodigy?

What else would I need to know, if I make the change over from the Voyager to the Prodigy?
