I just installed mine today, initally everything was totally fine, could pair it up and play music through pandora and everything. After a little bit the bluetooth stopped working and then after restarting it again, it was all greyed out and when I clicked the firmware update it said ------- as well. I found out that if you disconnect the battery and start it again, it seems to work but I dont want to have to disconnect and reconnect my battery everytime. I also got it from ebay too.. did you get your unit from dis_sound?
