Do you really need a GPS? I guess I'm showing my ignorance here but those little pocket maps that Rad Services handed out worked great. And that map in conjunction with mile markers, it's like you knew exactly where you were all the time. It was truly amazing!!!
If you worked for Rad Services, you probably were supplied with an abacus also....
Anyway, the GPS is more than just a directional helper.
You can set up traffic alerts.
You can set up your cellphone hands-free hrough the GPS.
Street by street announcements.
You can easily find restaurants, gas stations, post office, etc.
It is your personal navigator, and it can keep you from getting lost and finding the bad part of town.
