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.

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

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
