If you have an iPhone or Android phone, its SUPER easy to navigate to your destination. Just hold down the main button and say, "Navigate me to 123 Main St, Anytown, FL" and it will pull up your route and get you there. Or you can tell it to navigate you to Home Depot in Sarasota, FL. Or "navigate me home".
I like my Garmin GPS because it lets me update the maps 4 times per year for free, so it always has the most up to date maps. The map updates for the car software are $150 and are already behind the Garmin by a year. The phone maps are always up to date. I have found if you are in a area without cell coverage, and you don't already have the map downloaded to your phone, the phone GPS will be worthless.
