Have you ever tried the others?
This seems to be the problem I am having you see, everyone who has a tomtom says tomtom, Garmin and Navman likewise. People seem to stick with a brand...
i've had pretty much all of them over the last 5 years. tomtom is definately the best satnav for routes and user experience.
id try and get the tomtom go if possible.
i possible save up and go for the system nurrish provides.
check his post in the for sale section.
good luck
