I am installing a Dice ipod converter (to be placed in glove box), and at the same time would like to add an additional cigarette lighter outlet in the glove box. Preferably one that will not have power when the car ignition is off. This would be to run a Nuvi GPS, which I do not want to hardwire for when I go on trips.

This is in a 2006 A4 with the technology package/Sat/Bluetooth but no external CD changer.

A helpful person at work suggested that the power circuit for the radio was oversized and would be a good lace to splice into.

So, first, does anyone not think that is a good idea? And second, does anyone have a wiring diagram for the stereo harness so I know what wires to splice, and what gauge wire to use to run the cigarette lighter off of?

Anyone know of a good cigarette adapter you would recommend?

Thanks for any help!

 

very dependent on what system came in the car
