Navigon MobileNavigator for iPhone

@Barry Ward You beat me to it! Yes, the update has delivered on its promises. There's also the route planner in there, so you can set up a journey with multiple waypoints. The app is now mostly in line with Navigon's Windows Mobile equivalent, with the exception of the weather forecast and hotel booking facilities included with the latter. The most important thing is the safety camera data, though (and better GPS lock for those experiencing that problem, which I haven't been). I think my biggest criticism of MobileNavigator as it stands now with the update is that you can't navigate to a postcode alone, and the contacts link is still completely broken.

Agreed James. And why can't we just have a search option when searching for a location, where you can type in the name of a POI (such as "Chester Zoo" for example, or a post code, and it will come up with matches? Surely that will be very user-friendly. Other than that, I am now very happy with it.

Did a bit of digging on this, Interesting...

Downloaded MotionX GPS Lite to see how it performed on my iPhone.
Result: Pretty poorly, took ages to find a lock. Same as Navigon.

Turned off 3G in my phone settings:

Ran GPS Lite - A lock in seconds.
Ran Navigon - A lock within 20 secs, much better than before. Still drops the signal alot though.

Turned on 3G in my iPhone settings:
Tested again. Back to no GPS lock for ages.

I think there's a problem somewhere here. When 3G is switched on, the phones GPS performance is pretty poor, when not it's reasonably accurate. I've rebooted the phone a few times to check this out. Always the same results.

So what's the cause? the iPhone software? Hardware? who knows, but it would be interesting to find out if folks who are having GPS issues with an iPhone 3G with os 3.01 could test this out.

I bought this and it cannot get a GPS lock for more than 3 seconds every 3-5-minutes. Google maps tracks consistantly if I switch over showing that it is the software not the iPhone hardware. I complained to iTunes on the 16 Dep and demanded a refund but have not heard anything since. I am going to register a complaint to the government Consumer Direct website and I will sue them for a refund through the small claims court if nessisary. Appaling software and customer service.
