<VV> GPS error> Tires & Speedometers

[Ray Rodriguez III]

I also have a garmin nuvi 255 (mine is the "T" model).  I have checked it 
against mile markers several times and also driven through those automated 
radar sites, both showed that the GPS was quite accurate...  I would say 
certainly no more then 2mph error... I think its less than that even.  As a 
result I've been using the GPS (which also shows the speed limit on most 
roads) as my speedometer!  I actually wish you could set it to beep at you 
if you exceed the limit by more then 10mph...  its easy to get a silly 
ticket in a strange area.
