I replaced my Garmin 2610 and new Road Angel with a Nuvi 350 because i could enjoy their combined features in just one unit.
The Nuvi is very compact, will operate off its internal battery and includes speed camera warnings. It has clear mapping, excellent audio directions, fast satellite acquisition and is very easy to use.
I use it extensively in the UK and have taken it to France, Spain, Tenerife and Portugal where it proved invaluable.
The only thing I miss is that with the Garmin 2610 I could plan detailed routes which included a number of via points and download them to the sat-nav. With the Nuvi you can download waypoints - but not complete routes. I get around this by setting each required destination in sequence as I carry out the journey - a small price to pay for such a compact unit that slips into a shirt pocket.
