I bought a 360 recently and think it is excellent,sometimes a bit too good. I was in the uk last week and it got us around no problem,the ony ciricism I have is it will send you the shortest route possible,sometime down very narrow country lanes with grass going up the middle,you just pray you don't meet any on-coming traffic !.This is more down to the maps rather than the 360 itself,I looked at the settings but couldn't find a way to teel it to avoid these roads.
As I say sometimes its a bit too good,but well worth it for saving the inevitable arguements with your co-driver.
Paid €380 in halfords
