If you are looking for a no frills sat nav that is reliable and will get you to where you are going then this is the one to get. Having said that, this is my first sat nav, but I did a lot of research before opting for this one. I didn't need any extras, just wanted to get to places. It is the same as the which best buy 205 but with the addition of European maps (you could just get the cheaper regional 205 and add European maps if you needed them, but maps are more expensive to purchase as add-ons, than if you buy a model with them already on).
Having driven through London with this, it makes a potentially stressful journey quite easy. It has very clear on-screen mapping which gives you extra support for navigating around huge junctions. The voice is pleasant, and gives turn-by-turn directions. You can choose fastest route, direct route etc and it has a detour option to take you around any bad traffic or road works. It comes with screen mount, car charger (which also acts as the Arial for the traffic alerts), but as yet I'm not impressed with the traffic feature as it didn't pick up on a bad motorway hold up. However this feature is only as good as the information provided to it, so I guess this is not down to Garmin. It comes with a month of free speed camera alerts.
If you are looking for loads of extras, like mp3 player, speech to text etc then this doesn't have them so go for another model. I thought I wanted speech to text, but the road it directs you to turn into is written on the top of the map on this unit, so it does the job just fine.
The display has a daytime and night time view and will change automatically depending on the light, or you can set it to stay on your prefered view. It has a 3D and 2D map view, a pedestrian mode and a few other things like a currency convertor, places of interest, nearest places to eat, nearest petrol stations and shops.
All-in-all I love this, and I now look forward to driving without trying to balance maps and directions.
Cons
The traffic detection doesn't work as well as it should.
