Does anyone have a manufacturer for an in-dash SD card reader I can install next to my cigarette lighter that I can plug into an aftermarket receiver I am planning on purchasing? Garmin and SIMRAD make what I am looking for to read maps for their boat GPS navigation hardware. I am wondering if there is anything for cars for the head units to read MP3 and FLAC files? They make them for USB ports, but ideally, I am looking for a USB port and one SD card Port in a round dash mount format. Trying to find this thing is almost impossible and I find it crazy in this day and time since PC's have had these for a decade now.
