The left button shows your estimated arrival time, and tapping this gives you a range of odometer type details such as average speed, maximum speed, journey time and so on.
In all the whole thing felt smooth and intuitive to use during test trips, as far as navigation was concerned. I did have some issues with the added extras, though. The audio book player is tied in to Audible, the music player only like MP3s and the image viewer only likes JPEGs. You can find this out by trial and error or by downloading the full manual from the Web which lists file compatibility. Garmin really should have included this with the product, and we can’t forgive its failure to provide more than a printed quick reference guide in the box or even the manual on CD. Shame on you, Garmin.
As I said at the start of this review, Garmin has broken new ground with the nüvi 350, taking standalone navigation software into the realm of data storage and added features that is usually found in handhelds. It is a shame the file compatibility is not broader, but in general I like the idea. Mosy importantly though, Garmin has done a good job providing a competent navigation solution, which is its core business of. It is just a shame that, at such a high price, very few people are likely to be able to afford the purchase.
