XRoad G-Map app brings bona fide navigation to the iPhone
At long last, iPhone users who have grown increasingly frustrated by using Google Maps as their primary navigational tool can find relief... sort of. Available right now in the App Store, XRoad's G-Map application requires no internet connection whatsoever in order to function; rather, it packs oodles of maps into a 932MB package that covers most of western America and a few sporadic locales on the east. We're a bit baffled (and angered) by the not-at-all-comprehensive coverage, but we suppose we can expect updates to patch the gaps in the near future. It provides most of the same amenities you're used to seeing on real-deal GPS units, including POI editing, memo capabilities, location searching, etc. A word of caution, though: early reviews don't seem too stoked about it, so you may want to gloss it over good before hitting your card for $19.99.

That's one big ass jug handle/rotary/roundabout - depdending where you are from.
A sat nav app that isn't really sat-nav. FAIL
It is sat-nav, just the maps arent downloaded as they are displayed - they are in a database that lives ON the phone. You silly little man.
A comment proclaiming a failure when there isn't one? Fail!

Sorry, to defend Al here:
The software does NOT make use of real-time positioning. It gets your starting location, and then it "guesses" how long it'll take you to move to the next location based on the speed limit. If you miss a turn or get stuck in traffic, it just happily continues on. Apple has blocked use of the A-GPS chip for "navigation purposes" and this app didn't magically find it's way around.
according to the ap it says
"Automatic current location update through GPS Tracking"
If that doesn't mean turn by turn w/GPS can someone tell me what that means?
I definitely uses the GPS, it just does not sample frequently enough to detect small changes. For example it may think you're continuing on the highway for a few seconds, when you actually took an early exit. It will correct your position after a bit.
All GPS system use a combination of GPS signal, inertia and "snap to road" to keep your icon on the road in the display.
On the Building GPS systems I have in both my cars, I get the same problem, it's just a little more frequently in G-Maps.

Most of those poor marks hit the iTS before their new grading policy. Make sure you're good with the product - from the TOS, you're fighting in Seoul SK if you want your money back!
Wow, what ever happened to the TomTom nav app that was 'immanent' months and months ago?
Looks great for people who need to navigate around the Allied States of America.
