I like my VW - CD player and related are in the passenger glovebox so not that accessible, but it has 2 SD card readers - 1 for the maps, 1 for music. Right now it is 66 gigabytes on the SD card with room to spare (can't recall the size, but I want to say 128 GB) and it has slots molded into the plastic to store 4 more SD cards in the passenger glove box and 1 more in the driver's "glove box" (large enough for the paperwork). Haven't gotten it to skip yet, but it occasionally - 1X a month or so - will hang up between tracks for 5-10 seconds.
