I've had my F90BT for about a year with some minor mods. I recently had to send it back to Pioneer because it wasn't holding any information after vehicle turned off, car toys checked it out and confirmed.
ANyway, just got it back and stuck my SD back in to put the mods in place but it won't boot to it. THe unit boots normal. I've tried resetting but doesn't work either. I put a couple mp3s on the SD and the unit will play those once it boots.
What can I do to get back into testmode?
