Would would need an Inverter, kinda looks like an amp. This will allow you to convert your cars dc power into household ac current. Then you will need to find a suitable place to put it. I know that your car is kinda small so I would recommend the trunk. Then nyou would need a place to view it...
My neighbor had the same problem. She sent it to the dealer, who found a loose wire on the tranny. We all felt kinda dumb for not finding it ourselves. You could also have some broken shifter linkage.
Good luck
