Blame Kenwood if you never leave your car

The HDV990 is based on a 40GB hard drive

Japanese car-navigation systems are as advanced and over-specified as they are probably because no one's ever had theirs nicked from a parked vehicle before. That fact alone has to make Western drivers jealous enough before even considering the goodies in Kenwood 's new Smart Navi sat-nav systems.

The HDD Smart Navi Emotional Sound HDV990 (long name, isn't it?) costs JPY236,250 (£1,020) and is based on a 40GB hard drive. For that wad you get the usual excellent 3D/2D navigation system, a 7-inch wide LCD, a DVD player and an analogue TV tuner for starters.
