I've installed an RB1 into a 2001 Ram, and the Navigation doesn't work. It did work when it was installed in my 04 Rubicon.
It shows the vehicle changing direction (N,S E,W) but it does not show it moving on the map.
I'm guessing it's because the 2001 radio wiring does not have a speed sensor wire.

Any help greatly appreciated.

Try going to Pep Boys and look at their wiring schematics they have there. Bring a pen and paper too. No use buying it for 3 cents worth of info...
