mobile gps

I'm looking for a potable gps that has a realitivly big screen between 5-7 inches and has voice command or if a compsoite video out so I can plug it into a lcd screen. Voice command would be nice . But it has to have a 12 volt connection and be able to work without batteries and work on the cars battery. The reason being is that it will be in a center counsle and I'm not going to take the consule apart every 3 months to change out the batteries. I pefer a portable because I don't want to change receivers but if you all know of a reciever with the features I want lit your suggestions . I have a 1986 cadillac deville 4.1 and don't worry about fitment cause as long as its 12volt I can make it fit lol.1993 sdv
