Im about to buy my first Sat Nav and have been looking at the big three for under £200. Im taking the car to Brittany this year, so European maps would be handy. However, the ability to use it whilst walking round a strange town is just as important to me as getting there in the first place. I decided to cut out Garmin at an early stage because of a number of comments concerning its poor speaker output (Im getting a bit deaf in my old age). Any other views on this? That leaves the TomTom One Europe at around £180 or the Navman N40i, which Ive seen for £190. The irony is that the TomTom has a pedestrian mode, but only a 2 hr battery life, whereas the Navman has a 4.5 hr battery life but no pedestrian mode (i.e. it avoids taking you up one way streets even if you are on foot, and probably I dont know, Im only guessing has more difficulty keeping track of where you are at walking pace). Does anyone use theirs on foot and how do they perform? Is the Navman quoted battery life realistic?
