john2000s Posted July 9, 2014 Report Share Posted July 9, 2014 Hey folks, Have a bit of an issue I want to update my F900BT but when I place the SD card in the head unit, it is grey out. Anyone else experiencing this? I have tried 2 sd cards. Quote Link to post Share on other sites
MrBlueSky Posted August 24, 2014 Report Share Posted August 24, 2014 Yes I have the same....and that is with USB connected too....shame there is no replies........is yours formatted FAT32 ? I have the parking brake thing sorted so I get the menus, just no SD I haven't got an "old" SD unfortuntely so wondering about getting hold of something, but I would have though either the SD with adapter for microsd (1gb) and mini sd (also 1gb) ought to have worked ? I wonder if it has something to do with the SD card spec but as long as its not SDHC or something I can't see why Quote Link to post Share on other sites
MrBlueSky Posted August 25, 2014 Report Share Posted August 25, 2014 John, Bloody helpful lot on here aren't they ! Well I found if the SD is registered via the test mode, you can get to that with a USB. If you can't even get USB then you need to ensure you have parking brake correctly wired, or do the pin replacement trick (on the A/V connector, its involving switching pin 1 with pin4 and then making sure its earthed for the factory testing setup - there is a youtube video on the parking brack hack and a breakdown on here) I think you can update via USB anyway Quote Link to post Share on other sites
