Thinking of buying a new sat-nav or a sat-nav app for my iphone.

Currently using navfree which isn't bad but am quite interested in the lane guidance features on the newer commercial sat-navs.

Waze is quite nice in terms of reporting traffic but it falls down badly if it loses connection to the internet as it doesn't cache the route and it's routing is a bit funny (community driven).

Thing is the question is which one is worthwhile going for and also is it better to get an APP or buy a hardware unit?

The plus side of having it on my phone is I often have the phone connected to the car stereo for listening to music, so the voice prompts should come out of the car speakers, but the downside is it can really drain the battery and the Ipod port on my car doesn't always charge the phone as fast as using sat-nav can drain it.

I've had a Garmin and Tomtom units previously (infact still got the tomtom but don't use it due to being years out of date and also the window mount thing is broken on it.)

Any particular recommendations would be appreciated.. Even considering getting a cheap android handset for google maps as i used to have one and it always used to be pretty decent.
