Ford850 could I ask a favor, please say a bit about what you find better, nuvi vs iphone. One of my daughters has a nuvi and really likes it, I haven't even thought of a Garmin since getting the iphones. But am always ready to look at increased functionality. It would be helpful to know what you think having both.
I'll start with a disclaimer. I had my Garmin prior to my iphone, so I was already used to its features. Maybe there are apps for the iphone that have advantages, but for me (and when I watch friends use theirs) the Garmin wins.
- First I like the size of the GPS. The 7" screen is a monster. I use it on a bag type mount on the dash of my F150, with a permanent hidden power cord. It doesn't block any view and it is easy to read, even for back seat drivers

.
- The feature on the GPS that automatically splits the screen and adds a street view as you approach large exits etc is fantastic. They use actual photos so the signage, trees, and landmarks are shown just as you see them out your window. This is helpful in heavy traffic, confusing exits, and when you're stuck behind tall trucks etc.
- POI and other text can get cluttered on my phone, but the GPS is easier to navigate within the screens for me.
- There are more views, options, calculations, estimates, etc, on the GPS. Maybe the phone apps have them, but they are buried and not easily accessible while driving.
- Voice recognition is about equal between the 2 for me. I think they both work very well.
- Having the dedicated GPS frees up my phone. My GPS is waiting and ready when I get back in after a pit stop etc, picking up where I left off.
- Recalculating routes works better on the GPS for me. Some of that is due to the preference settings, so it knows my driving style.
- The traffic warnings on GPS are not great though, unless you are in a metro area. The radio coverage they use is hit and miss in other areas.
- My GPS can also be used as a phone. Never tried it, and don't plan to. I don't want a device that tries to do too many things, and that's what I think is happening to smart phones. I don't use my GPS as a phone, and I don't use my phone as a GPS in my vehicles.
When I bought my truck, I got the best touch screen dash option, but skipped the navigation package. I saved a ton, and if doing it again I would do the same. There are advantages to the built in nav, but not enough for me to justify the cost. I do like the free quarterly map updates on my Garmin.
