I'm looking at a new HU as i'm bored with my current one. I can't seem to find a decent unit which has a SD card slot. Currently I have a JVC which has an SD slot behind the front panel. Useful because it saves me buring cds.
I've been looking at the Alpine HU's none have an SD slot but most of them seem to have USB capability. I'm unsure about what this means. Do they have USB inputs in the rear somewhere? would I be able to purchase an extension lead or something similar to connect a memory card reader or a USB pen drive using this input or do they not work that way?
Anyone got any knowledge of these units?
