As a gadget freak I'm going to start listing the worst gadgets you can get for your car.
Feel free to add to the list.
Once this has dried out, i'll do a list of good ones

OK my first one has to be this:
At $2.45 delivered its a bargain not to be missed.
Sat Nav!? Pah who needs to spend hundreds on an electrical device when you can have this 'Cute Bear Window Mount compass!' Supplied with a suction cup its universal fit means you can take it between all your cars. Always heading south is a breeze with 'Cute Bear'.
The major advantage is the green hair, its pretty visible from outside the car so make sure you put in in the middle of the dash ensuring everyone can see it! Unlike Sat Nav - there is no need to remove this when you leave the car in a multi story for fear of theft, at this price no one would want to steal it they'd just order their own!
