iphone4 for navigation

[Jeff@QuadShop]

I've had Navigon since it came out and absolutely love it even when offroad. It works the same no matter if I have cell service or not.

MotionX is another great app for the iphone 4.

It allows you to preload maps. I did 900 miles of dirt on my motorcycle last year, mostly out of cell range and I was impressed to say the least. It also allow you to import tracks.

Another vote for Navigon here. Except the Address entry bit, and POI Search and the Google Assisted "Local Search", which is total rubbish, once you've finally manage to enter the address, it's flawless. The Navigon North America download comes with all maps built in, so it works no problem without a cellphone reception. This version costs a hefty $60, but at least to my personal experience, it's been absolutely worth it.

The traffic pack adds live traffic information and I've used it quite heavily during my commute. If there's traffic jams ahead, it will suggest alternative routes automatically.

It also learns your preferred routes based on your driving habits.

Navigon is an app that shows it's been designed and engineered the right way. It's a quite sophisticated piece of engineering, and even though the Address and POI entry are really bad, I still give it 2 thumbs up.

I've never used the POI search but address entry is pretty easy for me. Actually it's much easier than my Garmin 376c.

All I use for international travel is the iPhone. However, I do use a GPS for reliable tracking of our route. A high-quality GPS can also be necessary in areas of crevasse and mines.

I'll cast my vote for the Tom Tom for iPhone app. travelled all over Europe with it in the past year with the only problem being reception while walking the narrow alleys of Venice. It's interesting evn while on a boat it will direct you to the ferry channels to your next destination.

The combination of the offline maps of Tom Tom and the addition of the Lonely Planet guides are awesome.

Do any of the talking iPhone nav programs have an "avoid expressway" option? I wish navigon had that.

I have TopoMaps App on both my iPhone 4 and iPad 2. On the i4 it has consitantly give me accuracy that never had me doubting my location on the map. On the iPad 2 it has been absolutely spot on. My little blue dot never even leaving the dirt tracks I was driving. We were well outside any type of phone service outside of Moab UT.

Navigon does do that, it's under "options" "route profile"

I just used Gaia gps on my iPhone 4s this weekend. I was able to track my trail, look ahead on USGS topo maps with Forest Service overlay, and drop pins for waypoints in the future. All done without cell signal (I saved an area map of Big Bear before leaving while on WiFi for when you lose data). Worked excellent. So far I give it 10/10 for accuracy and it even tracked me through tall trees and from within my vehicle. Works pretty much like the Google map app the iPhones come with. Price: $10
