The satnav in my liberty requires me to be stationary to input into the satnav, I can be in gear and hand brake off, but as long as the car isnt in motion.........

I don't like the idea of being near anyone trying to operate a satnav while driving. However, the 'locking out' of entering destinations and other functions while in motion is annoying when your passenger is trying to use it.
When I get the time I have every intention of finding a way to bypass it.
I remember reading something a while ago on it, it was rather simple too, unfortunately I lost the link.
