My sweet wife, who understands my limitations, got me a portable Garmin Nuvi with a beanbag stand that I can sit on the dash of any car I may be driving. It has all the usual stuff for navigation, but my favorite thing about it is that there are two squares on the left of the screen. The top square displays the speed limit of wherever I am and the bottom displays the speed I’m driving. Both of these are very accurate. I was driving down the highway and the speed limit was changing from 65 to 55. Almost immediately after I passed the sign the Garmin changed the speed limit square from 65 to 55. Just a thought.
