They did try moving to mobiles, I used to have TomTom Navigator on my Symbian phone (Nokia N73), it worked quite well back then!

But you needed a seperate bluetooth GPS device because my phone didn't include a GPS-receiver.

Heck I own the TomTom Australia iPhone app, which I bought when visiting my parents who live out of mobile reception range. The maps were already much more accurate than Google when it came to rural tracks.
