Latest update.
According to supplier the 205w is the Widescreen version of the 205, and the 215 is just a newer model with almost the same features.
Got the box standard 205 for 70 squid, and it is much better than my friend's tomtom.
Tested it on 2 "shortcut routes" where tomtom sent me around the houses through what looked like alley ways and still managed to do a detour.
On both test runs, the garmin came up with the best route exactly as I know them, and gave the next best alternative every time I looped around a traffic jam.
Provided it lasts, very good value for money.
