Sat navs: Compare features & prices Garmin nuvi 40 review http://www.which.co.uk/technology/computing/reviews/sat-navs/garmin-nuvi-40/review/

The Nuvi 40 is an entry level product and priced as such. It does not have the features of the more expensive products. It is aimed at users who need a sat nav for the occasional journey, rather than professional travellers who will benefit from a more costly unit. If you bear this restriction in mind then the Nuvi40 is a useful product. I recently used the Nuvi 40 for two separate long distance journeys, and it took me flawlessly to both locations, and brought me home again. It does lack some features that I would like, such as the ability to avoid an entire area. I find the speed cam warnings so intrusive and annoying that I turned this feature off. I also found that the displayed map sometimes isn't aware of local road layouts; the map will tell you to go straight on, but when you arrive at the junction it's been laid out so the straight on route requires the left (or right) indicator. However, these are trivial issues considering the price of the unitThe latest version is now offered with a Lifetime Maps option, so that your unit never gets out of date. You can also report any map inaccuracies back to Garmin on their web site.If you need a cheap sat nav for the occasional journey then this is a viable option. Make sure you get the version with Lifetime Maps.

I am a delivery driver for ASDA. I needed a satnav which would accurately find the house within the street, including stating which side of the road it's on.At work there is an old Navman which I occasionally used when it was available. This was very good at finding the correct house. I bought the Garmin which I assumed would be equally good if not better.I used it last night for the first time and during a 16 drop delivery round it missed 9 houses by a long way, with 2 being at completely the wrong end of the street. In the dark, when trying to see small house numbers this is a huge problem.This alone is a huge disappointment but there are other issues. When you go off route I found it takes a long time (about 8 seconds) to recalculate the route. I know this doesn't sound like much but when you are in a busy area with lots of traffic this is an issue. I have experience of an old tomtom one xl, the old navman from work, and also a very old windows mobile phone running Co-Pilot V7 and all recalculate quicker than this.On the positive side, the screen is clear and bright and the sound is very clear. I found there weren't many options to configure compared to my old tomtom. This could be a good or bad thing depending on how much you like to tailor things to suit you. For example, I could not change map colour schemes or change the alert sounds.Overall a reasonable satnav for general use but if you need to find houses accurately then give this a miss.If PC World will take it back I will exchange it for a navman or mio which will hopefully find houses better.
