This was my first Sat Nav, having never used one before. First the mains charger stopped functioning and then the in-car charger gave up the ghost. The irritating problem is that it wont let you enter a full postcode for your destination. Say a postcode is AB1 1AB, - you can only enter AB1, and them have to scroll down dozens of roads within that postcode. Also this machine doesnt squeak when nearing speed traps which others do. It has the same problems as other sat navs re new roads as the maps are not up to date.
