Is Having GPS In The Radio Worth The Time and Money?

Very personal choice. As for me, I love my built in GPS on my F350. Large screen is very easy to read. And voice control by hitting a button on the steering wheel is great. Down side is the expense to upgrade maps. But I only do that every 2-3 years.

I used Garmins in the past, either windshield mount or dash mount on bean bag type base (preferred). And free map updates with some models. But I like the built in much better than one hanging from the windshield or sitting on the dash.
