Thank you shivedog for the tremendous help. I got it to work but the fix was in the ver 2.0 update folder. So here is a detailed guide of what I did to get my SD and USB to start picking up media files again. I am sure this will help out some poor fella like me because I was in a shitty mood the past 2 days and just wanted to kill myself. I beautifully installed it (with a little paint chip
) flushed inside my dash and now I couldn't play anything off of it. Anyways here goes.
As soon as I got my Avic without even thinking or testing any media files off of an SD card or a USB Drive, I downloaded and updated both the firmware (to Ver 2.0) and the bluetooth software of my AVIC-F500BT. I then tried playing media files off of it and the SD and USB would both remain greyed out. I plugged in a friends iPod and it got picked up immediately via USB. I searched and searched and read and my intuition told me that something got f'ed up when the update happened. I made a backup of my flash drive and downloaded the 1.0 flash disk zip file from the site shivedog posted above. I copied it onto my Avic's flash drive and rebooted it. It would stay at the pioneer screen and a System is loading.... screen would remain plastered at the bottom. I could only access the menu, system settings, and click on the map screen but couldn't click ok at the notice screen to get to the actual map. I loaded the ver 2.0 update folder on to my flash drive and rebooted. The update process completed and it rebooted. I checked under service information and it did say 2.0 so it did the update but the problem remained. Nothing worked. I then again booted into testmode and deleted everything off of my flash drive and then copied over the initial backup I had made of my system before doing any of this. I rebooted and everything was back to normal except for the SD and USB drive issue off course. That b***h still remained. So now I copied the ver 2.0 update folder again onto my SD card and booted into test mode. I then copied all the folders except PLT from the update folder and replaced the files in the folders, of the same name, in the flash drive. I rebooted again and lo and behold the SD card was picked up and I could play media files off of it. I was so happy I decided not to commit suicide.
I hope this helps.
Haris.
