I had a Mio sat nav that was all singing and dancing and then I had my new car, a Nissan Note with a built in sat nav. I gave my Mio to my Father as he is always speeding. I had it set to tell me 1 mile over the limit. My mums pleased because the sat nav is quite abrupt. I must say I realy like the new satnav in the Nissan. All I get now is a slight peep to warn me when something is approaching but thats all I need, it comes with cruise control and a limiter so there is no chance I could get a ticket. I wasn't impressed at first but it realy grows on you. The car has automatic lights. When these come on the sat nav dims, the Bluetooth phone connection is great with a mic built into the driving mirror and the best bit is my wife can set it while were driving.
A sat nav always improves a marriage don't you think
