I have a Pioneer DEH-5000UB
used to plug up my Nokia Node E73 to it for charging and MP3's on it. Kept on getting this message on the h.u. after a while of plugging up (Error - 19). So then I stopped and got myself a USB flash card reader from Fry's. Which was about maybe a month or two ago, WORKED GREAT ... until yesterday. I started to get the same message again (Error - 19). Tested the USB card reader and it doesn't even read ANY CARD (it says 5 in 1 but so far I have only used my Micro SD and a DLSR SD card in it - tried BOTH yesterday and NOTHING). I tested both cards - one via my cell to comp, WORKED. DSLR card, on my moms card reader WORKED.
Is my USB cord from the h.u. causing problems? The USB card reader died oddly yesterday. One minute I'm playing music fine like I usually do, and then within maybe 5 minutes of music it goes dead and I get the Error - 19 message on the h.u. Although this h.u. is fairly old, it still works like new imo. I baby it and ONLY use the remote. I sweat from time to time so I don't like putting finger prints all over it or the dash ... or pretty much anything in my truck.
