We went on a 2400 mile driving holiday using Navigon on the iPhone and never noticed this, it was always kept topped up. Maybe your charger doesn't provide enough power?So, took a trip to blackpool yesterday using Navigon. Plugged it in to the cigarette lighter at 98%. Got to blackpool at 68%. What's that all about? Is the power usage more than the charger can take? If so, thats totally usage for long journeys!!!

Does the charging symbol appear when it's plugged in to the charger?
YEah it does. I may have to get another cable.

Wait, did the Sat Nav end up taking you to Brighton or something? Why say it's useless, why not say 'Sat Nav is a battery drain'?
Calling something useless is very emotive and in these circumstances, is the wrong title for this thread!
Anyway, it sounds like your charger isn't drawing enough current to charge the phone.
Your thread title is both wrong and misleading.
Navigon is brilliant for the iPhone. YOU are have power supply problems in your car. While navigation take ~0.5-0.75% per minute use in my car when not plugged in, I have no problems when plugged into the car.
Admit it - you made a gross-overgeneralization in titling your thread. If I were a newbie reading titles, I might thinkk the overall the iPhone is "useless" for sat nav. The opposite is true. YOU have power (and thread title-ing) problems.
I have one of these Belkin Tunebase FMs that plugs into a socket in my car. I originally bought it for my iPod Classic before I got a stereo with an iPod connector built in. It works and charges my iPhone perfectly. I just get a popup saying the accessory is not made to work with the iPhone.

I figured since my Power Jolt charges both my iPod Classic and any model iPhone, the above Belkin Tunebase would also work with my iPhone since it works with my iPod. This is what I am using now as a mount when I use my GPS on the iPhone.
Then isn't the satnav useless on my iPhone as it stands? Hmm - sounds like! Regardless of the cause of the problem, it's still useless to me right now! Sounds like you have nothing better to do.
Sorry, but your thread title is misleading. This is a personal issue with a power adapter not providing adequate power and not a fault of the phone itself.
