Just bought a used head unit from LKQ, be warned they DO NOT sell them with the micro SD card.
It's also significantly more scratched up than the pictures showed, going to buy a headlight restoration kit and see if I can polish them out. Not going to bother buying a new card unless I can make this look presentable, and get it working in the car. Might as well turn a bad situation into a good one and use it as an opportunity to get an updated maps card
