Sat Nav Systems

[CK]

Hi Folks, looking for some advice b4 I take the plunge, any suggestions?
There are one or two features that I am seeking, Camera positions and speed indicators.
Also is there software package that I can download for a PSP, that enables you to use a PSP as a Sat Nav system, if there isn't there must be a gap in the market here, except that many owners of PSP's aren't old enough to drive.
Thanks in anticipation-CK
