Gee, we were just saying how competitive it is getting in the iPhone nav department, and Navigon has gone and cut prices for holiday travelers.

For 10 days only, beginning today (November 20-30) Navigon's iPhone app, Mobile Navigator [iTunes link]will be on sale for U.S. $69.99 instead of $89.99 providing a $20.00 savings. In addition, Navigon's Traffic Live feature is also on sale for $14.99 instead of $24.99. Traffic Live is a one time charge, not a continuing cost.

That's a significant saving for this very popular app, and puts it under similar featured apps from TomTom ($99.99) and Magellan ($79.99).

In my tests of the Navigon app I have found it accurate, and it has a superior user interface that is easy to use. Of course you shouldn't be looking at it while you are driving, and the text to speech does an excellent job of helping you keep your eyes on the road.

The Live Traffic feature will route you around major traffic congestion and adjust your ETA times.

It's nice to see prices heading south on some of these GPS packages. Now you'll be able to head south (or north, or any direction really) for less money and with more features. Have a safe trip.

It's coming! Navigon, maker of the iPhone Mobile Navigator app [iTunes link], will announce a live traffic feature tomorrow that will be rolled out next month. The update is only for the North American version of the software.

Our readers have absolutely lusted after this feature for iPhone navigation, and now, after already adding text to speech in an update earlier this month, Navigon has pulled ahead of the pack again.

According to the company:

The system 'uses real-time speed data from over one million drivers across North America including commercial fleets such as trucks and taxis but also regular drivers with a GPS system. So if for example several vehicles on a road report slow speed, the system recognizes congestion and provides an alternate and faster route.

The feature also uses an intelligent fusion of information from traffic cameras, speed sensors and conventional traffic messages coming through a radio network. In addition, the system includes historic traffic data to assist with the prediction of road conditions when calculating a route. This includes information about traffic conditions on certain holidays or yearly events, allowing the driver to avoid taking routes that traditionally are congested on a regular basis.

Navigon has announced that the traffic info, which they call Traffic Live, will be available as an in-app purchase for US$19.99 for the first 4 weeks it is offered, then it will cost $24.99 as a one time purchase with no other month to month service fees.

The software, which will run inside the $89.99 Mobile Navigator software, requires iPhone OS version 3.0 or greater.

Navigon has been very aggressive with this product, raising the bar every couple of weeks with some substantial free updates, and now some significant optional services. It will be interesting to see how Tom-Tom and some of the other navigation providers respond. The AT&T Navigator [iTunes link] app already includes real time traffic, but it is available only with a $9.99 a month subscription fee.

Users have been begging for it, and now Navigon has updated the Mobile Navigator [iTunes link] app to read street names to you as you drive.

I've tested the app around town, and it worked well, and the speech is clear and easy to understand. Here in Arizona, a lot of the street names are Spanish, and in most cases, the app pronounced them correctly.

It meant that I could drive around getting navigation instructions without ever looking at the iPhone screen, which is a real safety improvement.

Navigon has also added good iPod control functions. You can add new playlists or tracks, and listen while you are using navigation. This is an option that must be turned on, so if you want the function, be sure to do so.

I also like that the app now knows when it is night time and switches the display accordingly. Again, this is a feature you can use, or disable.

When I updated, the old version of the app was completely replaced, and the new app is 1.44 GB, so make sure you have the room and the time to get it downloaded.

Other features added to version 1.2.0 include the ability to email a destination to another Navigon user directly from the app. If the person gets the mail while on an iPhone and taps the location, it will launch the Mobile Navigator app and set the app for the forwarded destination.

Navigon has said the app would be US$99.00 the first of September, but the price is $89.99 instead, keeping it just under the $99.00 TomTom app, and reflecting, I think, how competitive navigation apps are getting with each other.

The company has also announced a car kit available in October, but few details and specs are known. This is the second update to Mobile Navigator since it has been released. Navigon says more updates will be coming. Traffic info and weather data would be nice.

In my view, with text to speech, Navigon has pulled ahead of the pack. I'd still like to see more points of interest in the database, and of course multi-tasking would be nice, but that is an Apple issue, not a Navigon issue.

I like this app, and it has been aggressively updated. Check it out if you are looking for nav, and if you already have this app, get on with the update.
