you must all be finished watching the 2nd part of the George doc by now. Any help appreciated.

Works very well on iPhone, good visuals and completely free. I have the Uk and Ireland, Germany and Italy and all have worked very well. I'm sure lots less features than a 'proper' sat nav but it does the job and at zero cost.

This works fine for me. I had a standalone TomTom unit up until recently, until it went kaput, and have been using CoPilot (on an iPhone 4) since then for trips up and down the country.

I actually prefer it to the TomTom and it is considerably cheaper. Occasionally it chooses a slightly strange route but if you do decide to go 'off piste' it seems to recognise better than the TomTom that you want to go a different way (ie it plots a new route based on your direction of travel rather than insisting you turn round)

I upgraded to the Premium version a while ago and it is better than the vanilla version, although that still does a good job at a pretty low price.

...for me too.
If you can forgive its very little foibles.
Like the voice saying "vyards" instead of "yards".
It's plenty good enough and a complete freebie.

I guess it depends upon what your intended usage is. Personally, I'm a huge fan of ViewRanger Ordnance-Survey-based mapping software (you can get it on iPhone, Android and even Symbian (remember that?)). Maps can be bought in a variety of ways or 'pay as you go' and there's mapping down to 1:25,000 which is perfect for hill-walking. It will, of course, hook you into GPS if you've got it, and you can record routes, do 'buddy beacon' stuff and even download guided walk details.

Great app, been using it on a variety of kit for a few years now. Also, the support is absolutely first-rate.

www.viewranger.com I think.
