Just at tip on GPS settings. I found that they put settings within settings under a generalized subject headers.
And MANY times what you are looking for is tucked under a subject heading that in your wildest dreams would you ever think it would be found there.
I sat down one day and clicked on all the headings and then clicked on all the subheadings subheadings and found about 40 more settings that really fine tuned my GPS.
I have an older TomTom with a huge screen and talk to speech so I don't have to hunt and peck to put my destinations in. And with the settings programmed correctly I use the GPS exclusively without incident now for 7 years on the road full timing!
After listening to all the problems every one is having with garmins I sure hope my TomTom lasts another 10 years!
