I recently bought me windshield mounted GPS to replace the hand held hiking/sport GPS I used to remember places.
The Car models have a memory that remembers your last destinations.
If you program in the location of ladies or spa's etc.. and use it to get to one (sometimes you are in the area and want to see "whats around" or you are not familiar with the area and she gave you the address so you program it) if the cops get ahold of it, they have a history of where your gps has been directing you to
