I for once have being using "Streets & trips" for 5 years now ,
and don't like it at all.(yes,i know , so why the 5 years... well at lease am not married to it...

)
last update i installed last year.
am going to buy into a GPS unit soon , Currently looking at the Nuvi 760 or 750 ,
lets demonstrate to you the advantage of buying into an upscale unit :
Here is a task , for anyone that have a GPS :
let us know the model you got !
then
Enter a trip form Zip : 08854
to Zip : 24153
Did your unit Route you throe WDC ?
at Street & trips you have to "Force" it to go on I-81 !!!
