I purchase in July last year from “StereoNeeds†a Pioneer F90BT Navigation DVD Receiver. It has worked perfectly up till this past week. The Secure Digital (SD) slot will no longer read the SD card. It recognizes that a SD card is present and displays the Screen for playing but no folders or detail files appear. I have tried 4 SD cards that all worked prior to this week. I have several issues one is that I used the SD slot and also all upgrades come via SD card.

Any Suggestions?

PS: I have tried resetting the unit several times using the reset button but it did not help.

Email stereoneeds they are autherized pioneer and will send your unit back for you under warranty

Thanks, I have plans to send it back to Pioneer. I have one other piece of information; the USB also does not work. Strange they both use the same player. I was wondering of it could be firmware but try to re-update but would not recognize the SD card.
