Thanks for all the replies
I don’t have an iPhone but my daughter has a newish iPod touch so will give the NavFree a try first before taking you up on the kind offers of a lend & see how I get on
Thanks again
The Touch doesn’t have GPS capability, I’m afraid.*
However, it’s possible to get it to work with a GPS unit that plugs into the 30-pin dock: http://gps.about.com/od/accessories/gr/Bad-Elf-GPS-iPad-iPod.htm
Not cheap, mind, so a borrowed unit might be your best option.
*And before anyone says it will work, yes, it can, by triangulation from cell towers and wifi hotspots, but accuracy will be woeful, certainly not what you want in a car.
