Good day to all.  I am still working out the bugs of my older F700BT that I installed in my 98 Lincoln Navigator about 2 months ago.  The issue that is driving me crazy now is that I hear no sound when playing music from an SD card,  The unit sees the card, I can change to the SD Card as the audio source, it plays the file, but no sound.  I've search this forum and the closest thing I can find is this thread:  http://avic411.com/index.php?/topic/26735-wont-play-any-music-off-my-sd-card-plz-help/?hl=port&do=findComment&comment=198203, but it is a slightly different issue.  The SD card is freshly formatted in FAT32 and all music files are mp3.  Any help would be greatly appreciated as the local radio stations are driving me CRAZY!!!!

Well, I too am very interested in this, although I have an F700BT.

Success!  I picked up a PNY 4GB SD card and I was able to update the firmware.  However, I cannot hear any sound from the SD card when I have music on it, but that will be another thread if I cannot find an answer.

Well, I think I just answered my own question.  Straight from the owners manual:

Good day to all.  I picked up a VERY out of date f700bt and I've had it running in my 98 Lincoln Navigaor for about a month now.  I am working through issues with the unit, using this site A LOT.  My issue now is that I cannot update the firmware on the unit.  I have the "LPUE080" folder on the top layer/folder of my SD card, the SD card is freshly formatted with FAT32, and there is nothing else on the card.  When I put the SD card in the slot on the unit, it does not start any update, but operates normally (playing music, etc).  I checked the A/V Source menu and the SD card is greyed out...basically the unit cannot see my SD card.  I thought I read somewhere on this forum that you had to "do something" (possibly the mute wire hack?) to get the SD card slot to become active, but I cannot find the same posts I saw when looking at other issues I have had.  I also thought I read somewhere that I cannot use an HCSD card...is that correct?  And today, I read again on this forum that the unit will not read certain brands of SD cards.  SO...I guess my main question is do I need a different SD card?
