heres a recent similiar thread http://www.ozhonda.com/forum/showthread.php?t=14661

I have an IPAQ with bluetooth GPS and Destinator 3 softare. It does pretty much exactly what the Navman PiN does. I am a consultant so it comes in handy for me when I go to see clients where I havnt been before. However mainly, I know how to get where Im going so its not really getting that much usage.

It is a cool gadget though

The software has its limits though. It has gotten me lost a couple of times directing me to dead ends and wanting me to do U turns on a one way street!
