Hi Guys! as many of you already know, I recently started work at a rural Sheriff's Office. While attempting to learn my countys roads, I discovered that My 10 year old Garmin Nuvi was woefully inadiquite for the task. It often shows roads that no longer exsist, or doesn't show roads that have been in constant use since the 1850's. Often the unit will just "zone out" and display nothing at all except the vehicle icon. I need a navigation unit that is up to date, and optimised for police work. Prefrably under $200. Any advice would be appreciated.
